Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622258, here are decompositions:

17 + 8622241 = 8622258
67 + 8622191 = 8622258
131 + 8622127 = 8622258
241 + 8622017 = 8622258
251 + 8622007 = 8622258
257 + 8622001 = 8622258
269 + 8621989 = 8622258
311 + 8621947 = 8622258

Showing the first eight; more decompositions exist.
