Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644422, here are decompositions:

179 + 8644243 = 8644422
191 + 8644231 = 8644422
251 + 8644171 = 8644422
331 + 8644091 = 8644422
373 + 8644049 = 8644422
431 + 8643991 = 8644422
463 + 8643959 = 8644422
499 + 8643923 = 8644422

Showing the first eight; more decompositions exist.
