Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624222, here are decompositions:

31 + 8624191 = 8624222
43 + 8624179 = 8624222
163 + 8624059 = 8624222
199 + 8624023 = 8624222
283 + 8623939 = 8624222
379 + 8623843 = 8624222
421 + 8623801 = 8624222
571 + 8623651 = 8624222

Showing the first eight; more decompositions exist.
