Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603966, here are decompositions:

3 + 8603963 = 8603966
13 + 8603953 = 8603966
73 + 8603893 = 8603966
127 + 8603839 = 8603966
199 + 8603767 = 8603966
277 + 8603689 = 8603966
373 + 8603593 = 8603966
433 + 8603533 = 8603966

Showing the first eight; more decompositions exist.
