Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651980, here are decompositions:

3 + 8651977 = 8651980
41 + 8651939 = 8651980
89 + 8651891 = 8651980
257 + 8651723 = 8651980
263 + 8651717 = 8651980
269 + 8651711 = 8651980
317 + 8651663 = 8651980
353 + 8651627 = 8651980

Showing the first eight; more decompositions exist.
