Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706918, here are decompositions:

37 + 8706881 = 8706918
47 + 8706871 = 8706918
89 + 8706829 = 8706918
127 + 8706791 = 8706918
167 + 8706751 = 8706918
191 + 8706727 = 8706918
211 + 8706707 = 8706918
251 + 8706667 = 8706918

Showing the first eight; more decompositions exist.
