Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511664, here are decompositions:

31 + 511633 = 511664
37 + 511627 = 511664
61 + 511603 = 511664
73 + 511591 = 511664
157 + 511507 = 511664
211 + 511453 = 511664
277 + 511387 = 511664
313 + 511351 = 511664

Showing the first eight; more decompositions exist.
