Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521598, here are decompositions:

17 + 521581 = 521598
31 + 521567 = 521598
41 + 521557 = 521598
47 + 521551 = 521598
59 + 521539 = 521598
61 + 521537 = 521598
71 + 521527 = 521598
79 + 521519 = 521598

Showing the first eight; more decompositions exist.
