Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631164, here are decompositions:

13 + 8631151 = 8631164
67 + 8631097 = 8631164
127 + 8631037 = 8631164
163 + 8631001 = 8631164
181 + 8630983 = 8631164
193 + 8630971 = 8631164
307 + 8630857 = 8631164
313 + 8630851 = 8631164

Showing the first eight; more decompositions exist.
