Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625678, here are decompositions:

29 + 8625649 = 8625678
37 + 8625641 = 8625678
41 + 8625637 = 8625678
79 + 8625599 = 8625678
137 + 8625541 = 8625678
151 + 8625527 = 8625678
157 + 8625521 = 8625678
199 + 8625479 = 8625678

Showing the first eight; more decompositions exist.
