Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651646, here are decompositions:

7 + 8651639 = 8651646
19 + 8651627 = 8651646
37 + 8651609 = 8651646
43 + 8651603 = 8651646
67 + 8651579 = 8651646
97 + 8651549 = 8651646
103 + 8651543 = 8651646
109 + 8651537 = 8651646

Showing the first eight; more decompositions exist.
