Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594160, here are decompositions:

79 + 31594081 = 31594160
97 + 31594063 = 31594160
223 + 31593937 = 31594160
229 + 31593931 = 31594160
373 + 31593787 = 31594160
397 + 31593763 = 31594160
439 + 31593721 = 31594160
457 + 31593703 = 31594160

Showing the first eight; more decompositions exist.
