Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500238, here are decompositions:

5 + 500233 = 500238
7 + 500231 = 500238
29 + 500209 = 500238
41 + 500197 = 500238
59 + 500179 = 500238
61 + 500177 = 500238
71 + 500167 = 500238
127 + 500111 = 500238

Showing the first eight; more decompositions exist.
