Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622186, here are decompositions:

59 + 8622127 = 8622186
73 + 8622113 = 8622186
163 + 8622023 = 8622186
179 + 8622007 = 8622186
197 + 8621989 = 8622186
227 + 8621959 = 8622186
239 + 8621947 = 8622186
317 + 8621869 = 8622186

Showing the first eight; more decompositions exist.
