Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521610, here are decompositions:

7 + 521603 = 521610
29 + 521581 = 521610
43 + 521567 = 521610
53 + 521557 = 521610
59 + 521551 = 521610
71 + 521539 = 521610
73 + 521537 = 521610
83 + 521527 = 521610

Showing the first eight; more decompositions exist.
