Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468016, here are decompositions:

3 + 31468013 = 31468016
67 + 31467949 = 31468016
79 + 31467937 = 31468016
163 + 31467853 = 31468016
457 + 31467559 = 31468016
757 + 31467259 = 31468016
787 + 31467229 = 31468016
859 + 31467157 = 31468016

Showing the first eight; more decompositions exist.
