Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631172, here are decompositions:

5 + 8631167 = 8631172
89 + 8631083 = 8631172
131 + 8631041 = 8631172
149 + 8631023 = 8631172
269 + 8630903 = 8631172
311 + 8630861 = 8631172
359 + 8630813 = 8631172
383 + 8630789 = 8631172

Showing the first eight; more decompositions exist.
