Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13722, here are decompositions:

11 + 13711 = 13722
13 + 13709 = 13722
29 + 13693 = 13722
31 + 13691 = 13722
41 + 13681 = 13722
43 + 13679 = 13722
53 + 13669 = 13722
73 + 13649 = 13722

Showing the first eight; more decompositions exist.
