Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637822, here are decompositions:

31 + 8637791 = 8637822
43 + 8637779 = 8637822
73 + 8637749 = 8637822
181 + 8637641 = 8637822
211 + 8637611 = 8637822
313 + 8637509 = 8637822
331 + 8637491 = 8637822
373 + 8637449 = 8637822

Showing the first eight; more decompositions exist.
