Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522408, here are decompositions:

17 + 522391 = 522408
37 + 522371 = 522408
71 + 522337 = 522408
127 + 522281 = 522408
149 + 522259 = 522408
157 + 522251 = 522408
179 + 522229 = 522408
181 + 522227 = 522408

Showing the first eight; more decompositions exist.
