Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22728, here are decompositions:

7 + 22721 = 22728
11 + 22717 = 22728
19 + 22709 = 22728
29 + 22699 = 22728
31 + 22697 = 22728
37 + 22691 = 22728
59 + 22669 = 22728
89 + 22639 = 22728

Showing the first eight; more decompositions exist.
