Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22042, here are decompositions:

3 + 22039 = 22042
5 + 22037 = 22042
11 + 22031 = 22042
29 + 22013 = 22042
113 + 21929 = 22042
131 + 21911 = 22042
149 + 21893 = 22042
179 + 21863 = 22042

Showing the first eight; more decompositions exist.
