Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624822, here are decompositions:

109 + 8624713 = 8624822
223 + 8624599 = 8624822
373 + 8624449 = 8624822
439 + 8624383 = 8624822
499 + 8624323 = 8624822
571 + 8624251 = 8624822
601 + 8624221 = 8624822
631 + 8624191 = 8624822

Showing the first eight; more decompositions exist.
