Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613966, here are decompositions:

5 + 8613961 = 8613966
7 + 8613959 = 8613966
13 + 8613953 = 8613966
19 + 8613947 = 8613966
37 + 8613929 = 8613966
73 + 8613893 = 8613966
79 + 8613887 = 8613966
103 + 8613863 = 8613966

Showing the first eight; more decompositions exist.
