Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38722, here are decompositions:

11 + 38711 = 38722
23 + 38699 = 38722
29 + 38693 = 38722
53 + 38669 = 38722
71 + 38651 = 38722
83 + 38639 = 38722
113 + 38609 = 38722
179 + 38543 = 38722

Showing the first eight; more decompositions exist.
