Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758686, here are decompositions:

17 + 8758669 = 8758686
89 + 8758597 = 8758686
103 + 8758583 = 8758686
109 + 8758577 = 8758686
113 + 8758573 = 8758686
137 + 8758549 = 8758686
149 + 8758537 = 8758686
173 + 8758513 = 8758686

Showing the first eight; more decompositions exist.
