Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594042, here are decompositions:

3 + 31594039 = 31594042
59 + 31593983 = 31594042
83 + 31593959 = 31594042
89 + 31593953 = 31594042
173 + 31593869 = 31594042
353 + 31593689 = 31594042
401 + 31593641 = 31594042
479 + 31593563 = 31594042

Showing the first eight; more decompositions exist.
