Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706870, here are decompositions:

17 + 8706853 = 8706870
37 + 8706833 = 8706870
41 + 8706829 = 8706870
47 + 8706823 = 8706870
79 + 8706791 = 8706870
127 + 8706743 = 8706870
163 + 8706707 = 8706870
199 + 8706671 = 8706870

Showing the first eight; more decompositions exist.
