Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656746, here are decompositions:

13 + 8656733 = 8656746
17 + 8656729 = 8656746
19 + 8656727 = 8656746
79 + 8656667 = 8656746
157 + 8656589 = 8656746
173 + 8656573 = 8656746
199 + 8656547 = 8656746
223 + 8656523 = 8656746

Showing the first eight; more decompositions exist.
