Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631384, here are decompositions:

5 + 8631379 = 8631384
11 + 8631373 = 8631384
17 + 8631367 = 8631384
43 + 8631341 = 8631384
53 + 8631331 = 8631384
101 + 8631283 = 8631384
107 + 8631277 = 8631384
137 + 8631247 = 8631384

Showing the first eight; more decompositions exist.
