Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20722, here are decompositions:

3 + 20719 = 20722
5 + 20717 = 20722
29 + 20693 = 20722
41 + 20681 = 20722
59 + 20663 = 20722
83 + 20639 = 20722
173 + 20549 = 20722
179 + 20543 = 20722

Showing the first eight; more decompositions exist.
