Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685742, here are decompositions:

3 + 8685739 = 8685742
5 + 8685737 = 8685742
11 + 8685731 = 8685742
59 + 8685683 = 8685742
83 + 8685659 = 8685742
89 + 8685653 = 8685742
113 + 8685629 = 8685742
173 + 8685569 = 8685742

Showing the first eight; more decompositions exist.
