Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28922, here are decompositions:

13 + 28909 = 28922
43 + 28879 = 28922
79 + 28843 = 28922
109 + 28813 = 28922
151 + 28771 = 28922
163 + 28759 = 28922
193 + 28729 = 28922
199 + 28723 = 28922

Showing the first eight; more decompositions exist.
