Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678756, here are decompositions:

3 + 8678753 = 8678756
7 + 8678749 = 8678756
43 + 8678713 = 8678756
157 + 8678599 = 8678756
199 + 8678557 = 8678756
283 + 8678473 = 8678756
397 + 8678359 = 8678756
433 + 8678323 = 8678756

Showing the first eight; more decompositions exist.
