Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522540, here are decompositions:

17 + 522523 = 522540
19 + 522521 = 522540
23 + 522517 = 522540
43 + 522497 = 522540
61 + 522479 = 522540
71 + 522469 = 522540
101 + 522439 = 522540
127 + 522413 = 522540

Showing the first eight; more decompositions exist.
