Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522440, here are decompositions:

31 + 522409 = 522440
67 + 522373 = 522440
103 + 522337 = 522440
151 + 522289 = 522440
157 + 522283 = 522440
181 + 522259 = 522440
211 + 522229 = 522440
229 + 522211 = 522440

Showing the first eight; more decompositions exist.
