Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508138, here are decompositions:

41 + 508097 = 508138
47 + 508091 = 508138
101 + 508037 = 508138
167 + 507971 = 508138
311 + 507827 = 508138
317 + 507821 = 508138
359 + 507779 = 508138
419 + 507719 = 508138

Showing the first eight; more decompositions exist.
