Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681964, here are decompositions:

7 + 8681957 = 8681964
23 + 8681941 = 8681964
41 + 8681923 = 8681964
107 + 8681857 = 8681964
113 + 8681851 = 8681964
127 + 8681837 = 8681964
227 + 8681737 = 8681964
233 + 8681731 = 8681964

Showing the first eight; more decompositions exist.
