Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502628, here are decompositions:

31 + 502597 = 502628
37 + 502591 = 502628
79 + 502549 = 502628
127 + 502501 = 502628
199 + 502429 = 502628
307 + 502321 = 502628
367 + 502261 = 502628
457 + 502171 = 502628

Showing the first eight; more decompositions exist.
