Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631622, here are decompositions:

5 + 8631617 = 8631622
11 + 8631611 = 8631622
23 + 8631599 = 8631622
53 + 8631569 = 8631622
89 + 8631533 = 8631622
281 + 8631341 = 8631622
353 + 8631269 = 8631622
431 + 8631191 = 8631622

Showing the first eight; more decompositions exist.
