Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630286, here are decompositions:

17 + 8630269 = 8630286
37 + 8630249 = 8630286
43 + 8630243 = 8630286
47 + 8630239 = 8630286
79 + 8630207 = 8630286
107 + 8630179 = 8630286
109 + 8630177 = 8630286
113 + 8630173 = 8630286

Showing the first eight; more decompositions exist.
