Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512528, here are decompositions:

7 + 512521 = 512528
31 + 512497 = 512528
61 + 512467 = 512528
109 + 512419 = 512528
139 + 512389 = 512528
241 + 512287 = 512528
277 + 512251 = 512528
619 + 511909 = 512528

Showing the first eight; more decompositions exist.
