Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632686, here are decompositions:

19 + 8632667 = 8632686
37 + 8632649 = 8632686
89 + 8632597 = 8632686
107 + 8632579 = 8632686
113 + 8632573 = 8632686
157 + 8632529 = 8632686
163 + 8632523 = 8632686
173 + 8632513 = 8632686

Showing the first eight; more decompositions exist.
