Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522688, here are decompositions:

11 + 522677 = 522688
29 + 522659 = 522688
167 + 522521 = 522688
191 + 522497 = 522688
239 + 522449 = 522688
317 + 522371 = 522688
449 + 522239 = 522688
461 + 522227 = 522688

Showing the first eight; more decompositions exist.
