Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515938, here are decompositions:

167 + 515771 = 515938
197 + 515741 = 515938
251 + 515687 = 515938
257 + 515681 = 515938
317 + 515621 = 515938
359 + 515579 = 515938
419 + 515519 = 515938
431 + 515507 = 515938

Showing the first eight; more decompositions exist.
