Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717918, here are decompositions:

37 + 8717881 = 8717918
61 + 8717857 = 8717918
109 + 8717809 = 8717918
127 + 8717791 = 8717918
151 + 8717767 = 8717918
229 + 8717689 = 8717918
241 + 8717677 = 8717918
367 + 8717551 = 8717918

Showing the first eight; more decompositions exist.
