Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522224, here are decompositions:

13 + 522211 = 522224
67 + 522157 = 522224
97 + 522127 = 522224
151 + 522073 = 522224
163 + 522061 = 522224
337 + 521887 = 522224
433 + 521791 = 522224
457 + 521767 = 522224

Showing the first eight; more decompositions exist.
