Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594072, here are decompositions:

11 + 31594061 = 31594072
23 + 31594049 = 31594072
89 + 31593983 = 31594072
113 + 31593959 = 31594072
233 + 31593839 = 31594072
239 + 31593833 = 31594072
353 + 31593719 = 31594072
383 + 31593689 = 31594072

Showing the first eight; more decompositions exist.
