Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513596, here are decompositions:

17 + 31513579 = 31513596
173 + 31513423 = 31513596
193 + 31513403 = 31513596
223 + 31513373 = 31513596
263 + 31513333 = 31513596
293 + 31513303 = 31513596
337 + 31513259 = 31513596
383 + 31513213 = 31513596

Showing the first eight; more decompositions exist.
