Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646008, here are decompositions:

37 + 8645971 = 8646008
67 + 8645941 = 8646008
109 + 8645899 = 8646008
421 + 8645587 = 8646008
577 + 8645431 = 8646008
601 + 8645407 = 8646008
727 + 8645281 = 8646008
739 + 8645269 = 8646008

Showing the first eight; more decompositions exist.
