Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682778, here are decompositions:

29 + 8682749 = 8682778
59 + 8682719 = 8682778
107 + 8682671 = 8682778
191 + 8682587 = 8682778
227 + 8682551 = 8682778
311 + 8682467 = 8682778
479 + 8682299 = 8682778
509 + 8682269 = 8682778

Showing the first eight; more decompositions exist.
