Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660686, here are decompositions:

3 + 8660683 = 8660686
5 + 8660681 = 8660686
29 + 8660657 = 8660686
107 + 8660579 = 8660686
149 + 8660537 = 8660686
179 + 8660507 = 8660686
263 + 8660423 = 8660686
317 + 8660369 = 8660686

Showing the first eight; more decompositions exist.
