Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631522, here are decompositions:

5 + 8631517 = 8631522
23 + 8631499 = 8631522
43 + 8631479 = 8631522
71 + 8631451 = 8631522
131 + 8631391 = 8631522
149 + 8631373 = 8631522
181 + 8631341 = 8631522
191 + 8631331 = 8631522

Showing the first eight; more decompositions exist.
