Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651944, here are decompositions:

3 + 8651941 = 8651944
5 + 8651939 = 8651944
53 + 8651891 = 8651944
173 + 8651771 = 8651944
227 + 8651717 = 8651944
233 + 8651711 = 8651944
251 + 8651693 = 8651944
281 + 8651663 = 8651944

Showing the first eight; more decompositions exist.
