Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508738, here are decompositions:

11 + 508727 = 508738
29 + 508709 = 508738
101 + 508637 = 508738
179 + 508559 = 508738
239 + 508499 = 508738
389 + 508349 = 508738
467 + 508271 = 508738
479 + 508259 = 508738

Showing the first eight; more decompositions exist.
