Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622442, here are decompositions:

29 + 8622413 = 8622442
83 + 8622359 = 8622442
89 + 8622353 = 8622442
149 + 8622293 = 8622442
233 + 8622209 = 8622442
251 + 8622191 = 8622442
401 + 8622041 = 8622442
419 + 8622023 = 8622442

Showing the first eight; more decompositions exist.
