Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594020, here are decompositions:

37 + 31593983 = 31594020
61 + 31593959 = 31594020
67 + 31593953 = 31594020
83 + 31593937 = 31594020
89 + 31593931 = 31594020
151 + 31593869 = 31594020
181 + 31593839 = 31594020
223 + 31593797 = 31594020

Showing the first eight; more decompositions exist.
