Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631040, here are decompositions:

3 + 8631037 = 8631040
17 + 8631023 = 8631040
23 + 8631017 = 8631040
29 + 8631011 = 8631040
137 + 8630903 = 8631040
179 + 8630861 = 8631040
227 + 8630813 = 8631040
251 + 8630789 = 8631040

Showing the first eight; more decompositions exist.
