Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631748, here are decompositions:

5 + 8631743 = 8631748
11 + 8631737 = 8631748
89 + 8631659 = 8631748
131 + 8631617 = 8631748
137 + 8631611 = 8631748
149 + 8631599 = 8631748
179 + 8631569 = 8631748
269 + 8631479 = 8631748

Showing the first eight; more decompositions exist.
