Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631858, here are decompositions:

7 + 8631851 = 8631858
71 + 8631787 = 8631858
89 + 8631769 = 8631858
199 + 8631659 = 8631858
229 + 8631629 = 8631858
241 + 8631617 = 8631858
359 + 8631499 = 8631858
379 + 8631479 = 8631858

Showing the first eight; more decompositions exist.
