Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708686, here are decompositions:

23 + 8708663 = 8708686
29 + 8708657 = 8708686
47 + 8708639 = 8708686
59 + 8708627 = 8708686
149 + 8708537 = 8708686
167 + 8708519 = 8708686
179 + 8708507 = 8708686
257 + 8708429 = 8708686

Showing the first eight; more decompositions exist.
