Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641966, here are decompositions:

17 + 8641949 = 8641966
83 + 8641883 = 8641966
149 + 8641817 = 8641966
233 + 8641733 = 8641966
257 + 8641709 = 8641966
269 + 8641697 = 8641966
293 + 8641673 = 8641966
353 + 8641613 = 8641966

Showing the first eight; more decompositions exist.
