Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681706, here are decompositions:

13 + 8681693 = 8681706
37 + 8681669 = 8681706
43 + 8681663 = 8681706
67 + 8681639 = 8681706
83 + 8681623 = 8681706
127 + 8681579 = 8681706
139 + 8681567 = 8681706
157 + 8681549 = 8681706

Showing the first eight; more decompositions exist.
