Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495724, here are decompositions:

31 + 31495693 = 31495724
61 + 31495663 = 31495724
67 + 31495657 = 31495724
223 + 31495501 = 31495724
277 + 31495447 = 31495724
307 + 31495417 = 31495724
367 + 31495357 = 31495724
373 + 31495351 = 31495724

Showing the first eight; more decompositions exist.
