Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681646, here are decompositions:

7 + 8681639 = 8681646
23 + 8681623 = 8681646
59 + 8681587 = 8681646
67 + 8681579 = 8681646
79 + 8681567 = 8681646
97 + 8681549 = 8681646
107 + 8681539 = 8681646
139 + 8681507 = 8681646

Showing the first eight; more decompositions exist.
