Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631306, here are decompositions:

23 + 8631283 = 8631306
29 + 8631277 = 8631306
37 + 8631269 = 8631306
59 + 8631247 = 8631306
107 + 8631199 = 8631306
113 + 8631193 = 8631306
139 + 8631167 = 8631306
197 + 8631109 = 8631306

Showing the first eight; more decompositions exist.
