Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622158, here are decompositions:

31 + 8622127 = 8622158
151 + 8622007 = 8622158
157 + 8622001 = 8622158
199 + 8621959 = 8622158
211 + 8621947 = 8622158
331 + 8621827 = 8622158
379 + 8621779 = 8622158
409 + 8621749 = 8622158

Showing the first eight; more decompositions exist.
