Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631344, here are decompositions:

3 + 8631341 = 8631344
13 + 8631331 = 8631344
37 + 8631307 = 8631344
61 + 8631283 = 8631344
67 + 8631277 = 8631344
97 + 8631247 = 8631344
151 + 8631193 = 8631344
193 + 8631151 = 8631344

Showing the first eight; more decompositions exist.
