Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715678, here are decompositions:

5 + 8715673 = 8715678
7 + 8715671 = 8715678
11 + 8715667 = 8715678
19 + 8715659 = 8715678
29 + 8715649 = 8715678
31 + 8715647 = 8715678
61 + 8715617 = 8715678
89 + 8715589 = 8715678

Showing the first eight; more decompositions exist.
