Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531746, here are decompositions:

19 + 31531727 = 31531746
67 + 31531679 = 31531746
79 + 31531667 = 31531746
97 + 31531649 = 31531746
107 + 31531639 = 31531746
167 + 31531579 = 31531746
223 + 31531523 = 31531746
263 + 31531483 = 31531746

Showing the first eight; more decompositions exist.
