Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641746, here are decompositions:

5 + 8641741 = 8641746
13 + 8641733 = 8641746
37 + 8641709 = 8641746
73 + 8641673 = 8641746
103 + 8641643 = 8641746
199 + 8641547 = 8641746
227 + 8641519 = 8641746
229 + 8641517 = 8641746

Showing the first eight; more decompositions exist.
