Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678660, here are decompositions:

61 + 8678599 = 8678660
73 + 8678587 = 8678660
79 + 8678581 = 8678660
103 + 8678557 = 8678660
307 + 8678353 = 8678660
337 + 8678323 = 8678660
349 + 8678311 = 8678660
457 + 8678203 = 8678660

Showing the first eight; more decompositions exist.
