Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678684, here are decompositions:

13 + 8678671 = 8678684
97 + 8678587 = 8678684
103 + 8678581 = 8678684
127 + 8678557 = 8678684
211 + 8678473 = 8678684
331 + 8678353 = 8678684
373 + 8678311 = 8678684
523 + 8678161 = 8678684

Showing the first eight; more decompositions exist.
