Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647746, here are decompositions:

7 + 8647739 = 8647746
47 + 8647699 = 8647746
89 + 8647657 = 8647746
157 + 8647589 = 8647746
167 + 8647579 = 8647746
179 + 8647567 = 8647746
277 + 8647469 = 8647746
337 + 8647409 = 8647746

Showing the first eight; more decompositions exist.
