Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690670, here are decompositions:

7 + 8690663 = 8690670
11 + 8690659 = 8690670
31 + 8690639 = 8690670
59 + 8690611 = 8690670
67 + 8690603 = 8690670
71 + 8690599 = 8690670
103 + 8690567 = 8690670
113 + 8690557 = 8690670

Showing the first eight; more decompositions exist.
