Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658618, here are decompositions:

5 + 8658613 = 8658618
29 + 8658589 = 8658618
37 + 8658581 = 8658618
41 + 8658577 = 8658618
47 + 8658571 = 8658618
149 + 8658469 = 8658618
401 + 8658217 = 8658618
457 + 8658161 = 8658618

Showing the first eight; more decompositions exist.
