Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631248, here are decompositions:

19 + 8631229 = 8631248
97 + 8631151 = 8631248
139 + 8631109 = 8631248
151 + 8631097 = 8631248
211 + 8631037 = 8631248
277 + 8630971 = 8631248
349 + 8630899 = 8631248
397 + 8630851 = 8631248

Showing the first eight; more decompositions exist.
