Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522320, here are decompositions:

3 + 522317 = 522320
31 + 522289 = 522320
37 + 522283 = 522320
61 + 522259 = 522320
109 + 522211 = 522320
163 + 522157 = 522320
193 + 522127 = 522320
241 + 522079 = 522320

Showing the first eight; more decompositions exist.
