Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678630, here are decompositions:

31 + 8678599 = 8678630
43 + 8678587 = 8678630
73 + 8678557 = 8678630
157 + 8678473 = 8678630
271 + 8678359 = 8678630
277 + 8678353 = 8678630
307 + 8678323 = 8678630
547 + 8678083 = 8678630

Showing the first eight; more decompositions exist.
