Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531702, here are decompositions:

23 + 31531679 = 31531702
53 + 31531649 = 31531702
179 + 31531523 = 31531702
281 + 31531421 = 31531702
401 + 31531301 = 31531702
431 + 31531271 = 31531702
563 + 31531139 = 31531702
701 + 31531001 = 31531702

Showing the first eight; more decompositions exist.
