Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615966, here are decompositions:

3 + 8615963 = 8615966
157 + 8615809 = 8615966
199 + 8615767 = 8615966
313 + 8615653 = 8615966
379 + 8615587 = 8615966
439 + 8615527 = 8615966
487 + 8615479 = 8615966
577 + 8615389 = 8615966

Showing the first eight; more decompositions exist.
