Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630642, here are decompositions:

3 + 8630639 = 8630642
43 + 8630599 = 8630642
151 + 8630491 = 8630642
193 + 8630449 = 8630642
199 + 8630443 = 8630642
331 + 8630311 = 8630642
373 + 8630269 = 8630642
463 + 8630179 = 8630642

Showing the first eight; more decompositions exist.
