Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637286, here are decompositions:

23 + 8637263 = 8637286
29 + 8637257 = 8637286
59 + 8637227 = 8637286
83 + 8637203 = 8637286
107 + 8637179 = 8637286
167 + 8637119 = 8637286
179 + 8637107 = 8637286
227 + 8637059 = 8637286

Showing the first eight; more decompositions exist.
