Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678782, here are decompositions:

3 + 8678779 = 8678782
5 + 8678777 = 8678782
23 + 8678759 = 8678782
29 + 8678753 = 8678782
41 + 8678741 = 8678782
83 + 8678699 = 8678782
89 + 8678693 = 8678782
113 + 8678669 = 8678782

Showing the first eight; more decompositions exist.
