Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678826, here are decompositions:

5 + 8678821 = 8678826
43 + 8678783 = 8678826
47 + 8678779 = 8678826
53 + 8678773 = 8678826
67 + 8678759 = 8678826
73 + 8678753 = 8678826
113 + 8678713 = 8678826
127 + 8678699 = 8678826

Showing the first eight; more decompositions exist.
