Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678784, here are decompositions:

5 + 8678779 = 8678784
7 + 8678777 = 8678784
11 + 8678773 = 8678784
31 + 8678753 = 8678784
43 + 8678741 = 8678784
71 + 8678713 = 8678784
83 + 8678701 = 8678784
113 + 8678671 = 8678784

Showing the first eight; more decompositions exist.
