Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500290, here are decompositions:

3 + 500287 = 500290
41 + 500249 = 500290
53 + 500237 = 500290
59 + 500231 = 500290
113 + 500177 = 500290
137 + 500153 = 500290
179 + 500111 = 500290
233 + 500057 = 500290

Showing the first eight; more decompositions exist.
