Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681676, here are decompositions:

7 + 8681669 = 8681676
13 + 8681663 = 8681676
37 + 8681639 = 8681676
53 + 8681623 = 8681676
89 + 8681587 = 8681676
97 + 8681579 = 8681676
109 + 8681567 = 8681676
127 + 8681549 = 8681676

Showing the first eight; more decompositions exist.
