Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631206, here are decompositions:

7 + 8631199 = 8631206
13 + 8631193 = 8631206
97 + 8631109 = 8631206
109 + 8631097 = 8631206
223 + 8630983 = 8631206
277 + 8630929 = 8631206
307 + 8630899 = 8631206
349 + 8630857 = 8631206

Showing the first eight; more decompositions exist.
