Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717042, here are decompositions:

31 + 8717011 = 8717042
43 + 8716999 = 8717042
151 + 8716891 = 8717042
181 + 8716861 = 8717042
199 + 8716843 = 8717042
223 + 8716819 = 8717042
283 + 8716759 = 8717042
349 + 8716693 = 8717042

Showing the first eight; more decompositions exist.
