Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631918, here are decompositions:

7 + 8631911 = 8631918
11 + 8631907 = 8631918
19 + 8631899 = 8631918
37 + 8631881 = 8631918
67 + 8631851 = 8631918
131 + 8631787 = 8631918
137 + 8631781 = 8631918
149 + 8631769 = 8631918

Showing the first eight; more decompositions exist.
