Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521682, here are decompositions:

11 + 521671 = 521682
13 + 521669 = 521682
23 + 521659 = 521682
41 + 521641 = 521682
79 + 521603 = 521682
101 + 521581 = 521682
131 + 521551 = 521682
149 + 521533 = 521682

Showing the first eight; more decompositions exist.
