Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631996, here are decompositions:

17 + 8631979 = 8631996
19 + 8631977 = 8631996
53 + 8631943 = 8631996
89 + 8631907 = 8631996
97 + 8631899 = 8631996
103 + 8631893 = 8631996
173 + 8631823 = 8631996
193 + 8631803 = 8631996

Showing the first eight; more decompositions exist.
