Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631028, here are decompositions:

5 + 8631023 = 8631028
11 + 8631017 = 8631028
17 + 8631011 = 8631028
167 + 8630861 = 8631028
191 + 8630837 = 8631028
239 + 8630789 = 8631028
257 + 8630771 = 8631028
269 + 8630759 = 8631028

Showing the first eight; more decompositions exist.
