Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631404, here are decompositions:

3 + 8631401 = 8631404
13 + 8631391 = 8631404
31 + 8631373 = 8631404
37 + 8631367 = 8631404
73 + 8631331 = 8631404
97 + 8631307 = 8631404
127 + 8631277 = 8631404
157 + 8631247 = 8631404

Showing the first eight; more decompositions exist.
