Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631832, here are decompositions:

29 + 8631803 = 8631832
89 + 8631743 = 8631832
173 + 8631659 = 8631832
233 + 8631599 = 8631832
263 + 8631569 = 8631832
353 + 8631479 = 8631832
431 + 8631401 = 8631832
491 + 8631341 = 8631832

Showing the first eight; more decompositions exist.
