Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20622, here are decompositions:

11 + 20611 = 20622
23 + 20599 = 20622
29 + 20593 = 20622
59 + 20563 = 20622
71 + 20551 = 20622
73 + 20549 = 20622
79 + 20543 = 20622
89 + 20533 = 20622

Showing the first eight; more decompositions exist.
