Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678732, here are decompositions:

19 + 8678713 = 8678732
31 + 8678701 = 8678732
61 + 8678671 = 8678732
151 + 8678581 = 8678732
373 + 8678359 = 8678732
379 + 8678353 = 8678732
409 + 8678323 = 8678732
421 + 8678311 = 8678732

Showing the first eight; more decompositions exist.
