Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512508, here are decompositions:

5 + 512503 = 512508
11 + 512497 = 512508
41 + 512467 = 512508
79 + 512429 = 512508
89 + 512419 = 512508
197 + 512311 = 512508
239 + 512269 = 512508
257 + 512251 = 512508

Showing the first eight; more decompositions exist.
