Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651982, here are decompositions:

5 + 8651977 = 8651982
23 + 8651959 = 8651982
29 + 8651953 = 8651982
41 + 8651941 = 8651982
43 + 8651939 = 8651982
89 + 8651893 = 8651982
113 + 8651869 = 8651982
179 + 8651803 = 8651982

Showing the first eight; more decompositions exist.
