Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631906, here are decompositions:

7 + 8631899 = 8631906
13 + 8631893 = 8631906
83 + 8631823 = 8631906
103 + 8631803 = 8631906
137 + 8631769 = 8631906
163 + 8631743 = 8631906
193 + 8631713 = 8631906
233 + 8631673 = 8631906

Showing the first eight; more decompositions exist.
