Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631536, here are decompositions:

3 + 8631533 = 8631536
19 + 8631517 = 8631536
37 + 8631499 = 8631536
157 + 8631379 = 8631536
163 + 8631373 = 8631536
229 + 8631307 = 8631536
307 + 8631229 = 8631536
337 + 8631199 = 8631536

Showing the first eight; more decompositions exist.
