Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681678, here are decompositions:

139 + 8681539 = 8681678
211 + 8681467 = 8681678
277 + 8681401 = 8681678
337 + 8681341 = 8681678
367 + 8681311 = 8681678
457 + 8681221 = 8681678
487 + 8681191 = 8681678
547 + 8681131 = 8681678

Showing the first eight; more decompositions exist.
