Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646158, here are decompositions:

97 + 8646061 = 8646158
271 + 8645887 = 8646158
397 + 8645761 = 8646158
439 + 8645719 = 8646158
541 + 8645617 = 8646158
571 + 8645587 = 8646158
709 + 8645449 = 8646158
727 + 8645431 = 8646158

Showing the first eight; more decompositions exist.
