Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678456, here are decompositions:

97 + 8678359 = 8678456
103 + 8678353 = 8678456
277 + 8678179 = 8678456
307 + 8678149 = 8678456
373 + 8678083 = 8678456
463 + 8677993 = 8678456
733 + 8677723 = 8678456
1063 + 8677393 = 8678456

Showing the first eight; more decompositions exist.
