Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631912, here are decompositions:

5 + 8631907 = 8631912
13 + 8631899 = 8631912
19 + 8631893 = 8631912
31 + 8631881 = 8631912
61 + 8631851 = 8631912
89 + 8631823 = 8631912
109 + 8631803 = 8631912
131 + 8631781 = 8631912

Showing the first eight; more decompositions exist.
