Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646218, here are decompositions:

37 + 8646181 = 8646218
157 + 8646061 = 8646218
277 + 8645941 = 8646218
331 + 8645887 = 8646218
457 + 8645761 = 8646218
499 + 8645719 = 8646218
571 + 8645647 = 8646218
601 + 8645617 = 8646218

Showing the first eight; more decompositions exist.
