Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631272, here are decompositions:

3 + 8631269 = 8631272
43 + 8631229 = 8631272
73 + 8631199 = 8631272
79 + 8631193 = 8631272
163 + 8631109 = 8631272
271 + 8631001 = 8631272
373 + 8630899 = 8631272
421 + 8630851 = 8631272

Showing the first eight; more decompositions exist.
