Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531924, here are decompositions:

3 + 31531921 = 31531924
41 + 31531883 = 31531924
107 + 31531817 = 31531924
173 + 31531751 = 31531924
197 + 31531727 = 31531924
257 + 31531667 = 31531924
401 + 31531523 = 31531924
467 + 31531457 = 31531924

Showing the first eight; more decompositions exist.
