Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511088, here are decompositions:

31 + 511057 = 511088
157 + 510931 = 511088
181 + 510907 = 511088
199 + 510889 = 511088
241 + 510847 = 511088
271 + 510817 = 511088
337 + 510751 = 511088
379 + 510709 = 511088

Showing the first eight; more decompositions exist.
