Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631132, here are decompositions:

23 + 8631109 = 8631132
109 + 8631023 = 8631132
131 + 8631001 = 8631132
149 + 8630983 = 8631132
229 + 8630903 = 8631132
233 + 8630899 = 8631132
271 + 8630861 = 8631132
281 + 8630851 = 8631132

Showing the first eight; more decompositions exist.
