Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641960, here are decompositions:

3 + 8641957 = 8641960
11 + 8641949 = 8641960
179 + 8641781 = 8641960
227 + 8641733 = 8641960
251 + 8641709 = 8641960
263 + 8641697 = 8641960
317 + 8641643 = 8641960
347 + 8641613 = 8641960

Showing the first eight; more decompositions exist.
