Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631212, here are decompositions:

13 + 8631199 = 8631212
19 + 8631193 = 8631212
61 + 8631151 = 8631212
103 + 8631109 = 8631212
211 + 8631001 = 8631212
229 + 8630983 = 8631212
241 + 8630971 = 8631212
283 + 8630929 = 8631212

Showing the first eight; more decompositions exist.
