Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495924, here are decompositions:

3 + 31495921 = 31495924
167 + 31495757 = 31495924
191 + 31495733 = 31495924
233 + 31495691 = 31495924
263 + 31495661 = 31495924
401 + 31495523 = 31495924
431 + 31495493 = 31495924
443 + 31495481 = 31495924

Showing the first eight; more decompositions exist.
