Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678772, here are decompositions:

13 + 8678759 = 8678772
19 + 8678753 = 8678772
23 + 8678749 = 8678772
31 + 8678741 = 8678772
59 + 8678713 = 8678772
71 + 8678701 = 8678772
73 + 8678699 = 8678772
79 + 8678693 = 8678772

Showing the first eight; more decompositions exist.
