Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630748, here are decompositions:

11 + 8630737 = 8630748
79 + 8630669 = 8630748
101 + 8630647 = 8630748
107 + 8630641 = 8630748
109 + 8630639 = 8630748
149 + 8630599 = 8630748
157 + 8630591 = 8630748
229 + 8630519 = 8630748

Showing the first eight; more decompositions exist.
