Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631264, here are decompositions:

13 + 8631251 = 8631264
17 + 8631247 = 8631264
71 + 8631193 = 8631264
73 + 8631191 = 8631264
97 + 8631167 = 8631264
113 + 8631151 = 8631264
167 + 8631097 = 8631264
181 + 8631083 = 8631264

Showing the first eight; more decompositions exist.
