Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594228, here are decompositions:

131 + 31594097 = 31594228
167 + 31594061 = 31594228
179 + 31594049 = 31594228
269 + 31593959 = 31594228
359 + 31593869 = 31594228
389 + 31593839 = 31594228
431 + 31593797 = 31594228
461 + 31593767 = 31594228

Showing the first eight; more decompositions exist.
