Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630644, here are decompositions:

3 + 8630641 = 8630644
5 + 8630639 = 8630644
53 + 8630591 = 8630644
167 + 8630477 = 8630644
227 + 8630417 = 8630644
257 + 8630387 = 8630644
353 + 8630291 = 8630644
401 + 8630243 = 8630644

Showing the first eight; more decompositions exist.
