Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631504, here are decompositions:

5 + 8631499 = 8631504
53 + 8631451 = 8631504
103 + 8631401 = 8631504
113 + 8631391 = 8631504
131 + 8631373 = 8631504
137 + 8631367 = 8631504
163 + 8631341 = 8631504
173 + 8631331 = 8631504

Showing the first eight; more decompositions exist.
