Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627286, here are decompositions:

29 + 8627257 = 8627286
43 + 8627243 = 8627286
113 + 8627173 = 8627286
137 + 8627149 = 8627286
139 + 8627147 = 8627286
167 + 8627119 = 8627286
229 + 8627057 = 8627286
257 + 8627029 = 8627286

Showing the first eight; more decompositions exist.
