Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521562, here are decompositions:

5 + 521557 = 521562
11 + 521551 = 521562
23 + 521539 = 521562
29 + 521533 = 521562
43 + 521519 = 521562
59 + 521503 = 521562
71 + 521491 = 521562
79 + 521483 = 521562

Showing the first eight; more decompositions exist.
