Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502668, here are decompositions:

17 + 502651 = 502668
37 + 502631 = 502668
71 + 502597 = 502668
151 + 502517 = 502668
167 + 502501 = 502668
181 + 502487 = 502668
227 + 502441 = 502668
239 + 502429 = 502668

Showing the first eight; more decompositions exist.
