Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531696, here are decompositions:

17 + 31531679 = 31531696
29 + 31531667 = 31531696
47 + 31531649 = 31531696
173 + 31531523 = 31531696
239 + 31531457 = 31531696
293 + 31531403 = 31531696
479 + 31531217 = 31531696
557 + 31531139 = 31531696

Showing the first eight; more decompositions exist.
