Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22090, here are decompositions:

11 + 22079 = 22090
17 + 22073 = 22090
23 + 22067 = 22090
53 + 22037 = 22090
59 + 22031 = 22090
113 + 21977 = 22090
179 + 21911 = 22090
197 + 21893 = 22090

Showing the first eight; more decompositions exist.
