Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622422, here are decompositions:

31 + 8622391 = 8622422
43 + 8622379 = 8622422
79 + 8622343 = 8622422
181 + 8622241 = 8622422
199 + 8622223 = 8622422
421 + 8622001 = 8622422
433 + 8621989 = 8622422
439 + 8621983 = 8622422

Showing the first eight; more decompositions exist.
