Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631558, here are decompositions:

41 + 8631517 = 8631558
59 + 8631499 = 8631558
79 + 8631479 = 8631558
107 + 8631451 = 8631558
157 + 8631401 = 8631558
167 + 8631391 = 8631558
179 + 8631379 = 8631558
191 + 8631367 = 8631558

Showing the first eight; more decompositions exist.
