Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646986, here are decompositions:

37 + 8646949 = 8646986
43 + 8646943 = 8646986
97 + 8646889 = 8646986
163 + 8646823 = 8646986
193 + 8646793 = 8646986
277 + 8646709 = 8646986
379 + 8646607 = 8646986
457 + 8646529 = 8646986

Showing the first eight; more decompositions exist.
