Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522228, here are decompositions:

17 + 522211 = 522228
29 + 522199 = 522228
37 + 522191 = 522228
61 + 522167 = 522228
67 + 522161 = 522228
71 + 522157 = 522228
101 + 522127 = 522228
149 + 522079 = 522228

Showing the first eight; more decompositions exist.
