Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707666, here are decompositions:

5 + 8707661 = 8707666
17 + 8707649 = 8707666
59 + 8707607 = 8707666
389 + 8707277 = 8707666
563 + 8707103 = 8707666
659 + 8707007 = 8707666
683 + 8706983 = 8707666
719 + 8706947 = 8707666

Showing the first eight; more decompositions exist.
