Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500918, here are decompositions:

7 + 500911 = 500918
31 + 500887 = 500918
37 + 500881 = 500918
79 + 500839 = 500918
109 + 500809 = 500918
127 + 500791 = 500918
199 + 500719 = 500918
241 + 500677 = 500918

Showing the first eight; more decompositions exist.
