Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631474, here are decompositions:

23 + 8631451 = 8631474
73 + 8631401 = 8631474
83 + 8631391 = 8631474
101 + 8631373 = 8631474
107 + 8631367 = 8631474
167 + 8631307 = 8631474
191 + 8631283 = 8631474
197 + 8631277 = 8631474

Showing the first eight; more decompositions exist.
