Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631158, here are decompositions:

7 + 8631151 = 8631158
61 + 8631097 = 8631158
157 + 8631001 = 8631158
229 + 8630929 = 8631158
307 + 8630851 = 8631158
337 + 8630821 = 8631158
379 + 8630779 = 8631158
409 + 8630749 = 8631158

Showing the first eight; more decompositions exist.
