Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631548, here are decompositions:

31 + 8631517 = 8631548
97 + 8631451 = 8631548
157 + 8631391 = 8631548
181 + 8631367 = 8631548
229 + 8631319 = 8631548
241 + 8631307 = 8631548
271 + 8631277 = 8631548
349 + 8631199 = 8631548

Showing the first eight; more decompositions exist.
