Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20962, here are decompositions:

3 + 20959 = 20962
23 + 20939 = 20962
41 + 20921 = 20962
59 + 20903 = 20962
83 + 20879 = 20962
89 + 20873 = 20962
113 + 20849 = 20962
173 + 20789 = 20962

Showing the first eight; more decompositions exist.
