I'd write that like this ;-)

int[0] x = [ 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41,
		43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101,
		103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157,
		163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223,
		227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277,
		281, 283, 293, 307, 311, 313, 317, 331, 337, 347, 349,
		353, 359, 367, 373, 379, 383, 389, 397, 401, 409, 419,
		421, 431, 433, 439, 443, 449, 457, 461, 463, 467, 479,
		487, 491, 499, 503, 509, 521, 523, 541 ];

..let the compiler count them ;-)
