Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661930, here are decompositions:

29 + 8661901 = 8661930
31 + 8661899 = 8661930
41 + 8661889 = 8661930
47 + 8661883 = 8661930
59 + 8661871 = 8661930
89 + 8661841 = 8661930
131 + 8661799 = 8661930
163 + 8661767 = 8661930

Showing the first eight; more decompositions exist.
