Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631960, here are decompositions:

17 + 8631943 = 8631960
53 + 8631907 = 8631960
61 + 8631899 = 8631960
67 + 8631893 = 8631960
79 + 8631881 = 8631960
109 + 8631851 = 8631960
137 + 8631823 = 8631960
157 + 8631803 = 8631960

Showing the first eight; more decompositions exist.
