Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646618, here are decompositions:

11 + 8646607 = 8646618
37 + 8646581 = 8646618
47 + 8646571 = 8646618
59 + 8646559 = 8646618
89 + 8646529 = 8646618
107 + 8646511 = 8646618
131 + 8646487 = 8646618
139 + 8646479 = 8646618

Showing the first eight; more decompositions exist.
