Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678672, here are decompositions:

3 + 8678669 = 8678672
73 + 8678599 = 8678672
199 + 8678473 = 8678672
313 + 8678359 = 8678672
349 + 8678323 = 8678672
523 + 8678149 = 8678672
619 + 8678053 = 8678672
643 + 8678029 = 8678672

Showing the first eight; more decompositions exist.
