Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631356, here are decompositions:

37 + 8631319 = 8631356
73 + 8631283 = 8631356
79 + 8631277 = 8631356
109 + 8631247 = 8631356
127 + 8631229 = 8631356
157 + 8631199 = 8631356
163 + 8631193 = 8631356
373 + 8630983 = 8631356

Showing the first eight; more decompositions exist.
