Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20772, here are decompositions:

13 + 20759 = 20772
19 + 20753 = 20772
23 + 20749 = 20772
29 + 20743 = 20772
41 + 20731 = 20772
53 + 20719 = 20772
79 + 20693 = 20772
109 + 20663 = 20772

Showing the first eight; more decompositions exist.
