Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618966, here are decompositions:

7 + 8618959 = 8618966
43 + 8618923 = 8618966
73 + 8618893 = 8618966
157 + 8618809 = 8618966
229 + 8618737 = 8618966
277 + 8618689 = 8618966
283 + 8618683 = 8618966
373 + 8618593 = 8618966

Showing the first eight; more decompositions exist.
