Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449814, here are decompositions:

23 + 31449791 = 31449814
47 + 31449767 = 31449814
113 + 31449701 = 31449814
167 + 31449647 = 31449814
233 + 31449581 = 31449814
257 + 31449557 = 31449814
491 + 31449323 = 31449814
743 + 31449071 = 31449814

Showing the first eight; more decompositions exist.
