Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631774, here are decompositions:

5 + 8631769 = 8631774
31 + 8631743 = 8631774
37 + 8631737 = 8631774
61 + 8631713 = 8631774
101 + 8631673 = 8631774
157 + 8631617 = 8631774
163 + 8631611 = 8631774
241 + 8631533 = 8631774

Showing the first eight; more decompositions exist.
