Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20562, here are decompositions:

11 + 20551 = 20562
13 + 20549 = 20562
19 + 20543 = 20562
29 + 20533 = 20562
41 + 20521 = 20562
53 + 20509 = 20562
79 + 20483 = 20562
83 + 20479 = 20562

Showing the first eight; more decompositions exist.
