Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631982, here are decompositions:

3 + 8631979 = 8631982
5 + 8631977 = 8631982
71 + 8631911 = 8631982
83 + 8631899 = 8631982
89 + 8631893 = 8631982
101 + 8631881 = 8631982
131 + 8631851 = 8631982
179 + 8631803 = 8631982

Showing the first eight; more decompositions exist.
