Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502786, here are decompositions:

5 + 502781 = 502786
17 + 502769 = 502786
83 + 502703 = 502786
173 + 502613 = 502786
233 + 502553 = 502786
269 + 502517 = 502786
509 + 502277 = 502786
569 + 502217 = 502786

Showing the first eight; more decompositions exist.
