Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631476, here are decompositions:

97 + 8631379 = 8631476
103 + 8631373 = 8631476
109 + 8631367 = 8631476
157 + 8631319 = 8631476
193 + 8631283 = 8631476
199 + 8631277 = 8631476
229 + 8631247 = 8631476
277 + 8631199 = 8631476

Showing the first eight; more decompositions exist.
