Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678726, here are decompositions:

13 + 8678713 = 8678726
19 + 8678707 = 8678726
127 + 8678599 = 8678726
139 + 8678587 = 8678726
367 + 8678359 = 8678726
373 + 8678353 = 8678726
523 + 8678203 = 8678726
547 + 8678179 = 8678726

Showing the first eight; more decompositions exist.
