Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657670, here are decompositions:

19 + 8657651 = 8657670
31 + 8657639 = 8657670
37 + 8657633 = 8657670
41 + 8657629 = 8657670
59 + 8657611 = 8657670
101 + 8657569 = 8657670
103 + 8657567 = 8657670
107 + 8657563 = 8657670

Showing the first eight; more decompositions exist.
