Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686746, here are decompositions:

17 + 8686729 = 8686746
43 + 8686703 = 8686746
59 + 8686687 = 8686746
67 + 8686679 = 8686746
157 + 8686589 = 8686746
179 + 8686567 = 8686746
283 + 8686463 = 8686746
337 + 8686409 = 8686746

Showing the first eight; more decompositions exist.
