Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707778, here are decompositions:

31 + 8707747 = 8707778
67 + 8707711 = 8707778
109 + 8707669 = 8707778
127 + 8707651 = 8707778
199 + 8707579 = 8707778
241 + 8707537 = 8707778
349 + 8707429 = 8707778
421 + 8707357 = 8707778

Showing the first eight; more decompositions exist.
