Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646980, here are decompositions:

19 + 8646961 = 8646980
31 + 8646949 = 8646980
37 + 8646943 = 8646980
127 + 8646853 = 8646980
157 + 8646823 = 8646980
163 + 8646817 = 8646980
229 + 8646751 = 8646980
271 + 8646709 = 8646980

Showing the first eight; more decompositions exist.
