Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646612, here are decompositions:

5 + 8646607 = 8646612
31 + 8646581 = 8646612
41 + 8646571 = 8646612
53 + 8646559 = 8646612
83 + 8646529 = 8646612
101 + 8646511 = 8646612
109 + 8646503 = 8646612
211 + 8646401 = 8646612

Showing the first eight; more decompositions exist.
