Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651670, here are decompositions:

7 + 8651663 = 8651670
23 + 8651647 = 8651670
31 + 8651639 = 8651670
43 + 8651627 = 8651670
61 + 8651609 = 8651670
67 + 8651603 = 8651670
89 + 8651581 = 8651670
127 + 8651543 = 8651670

Showing the first eight; more decompositions exist.
