Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622426, here are decompositions:

5 + 8622421 = 8622426
13 + 8622413 = 8622426
47 + 8622379 = 8622426
53 + 8622373 = 8622426
67 + 8622359 = 8622426
73 + 8622353 = 8622426
83 + 8622343 = 8622426
89 + 8622337 = 8622426

Showing the first eight; more decompositions exist.
