Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641654, here are decompositions:

3 + 8641651 = 8641654
11 + 8641643 = 8641654
23 + 8641631 = 8641654
41 + 8641613 = 8641654
83 + 8641571 = 8641654
107 + 8641547 = 8641654
113 + 8641541 = 8641654
137 + 8641517 = 8641654

Showing the first eight; more decompositions exist.
