Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631470, here are decompositions:

19 + 8631451 = 8631470
79 + 8631391 = 8631470
97 + 8631373 = 8631470
103 + 8631367 = 8631470
139 + 8631331 = 8631470
151 + 8631319 = 8631470
163 + 8631307 = 8631470
193 + 8631277 = 8631470

Showing the first eight; more decompositions exist.
