Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615678, here are decompositions:

139 + 8615539 = 8615678
151 + 8615527 = 8615678
199 + 8615479 = 8615678
541 + 8615137 = 8615678
661 + 8615017 = 8615678
691 + 8614987 = 8615678
727 + 8614951 = 8615678
739 + 8614939 = 8615678

Showing the first eight; more decompositions exist.
