Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449716, here are decompositions:

19 + 31449697 = 31449716
37 + 31449679 = 31449716
43 + 31449673 = 31449716
79 + 31449637 = 31449716
97 + 31449619 = 31449716
127 + 31449589 = 31449716
139 + 31449577 = 31449716
163 + 31449553 = 31449716

Showing the first eight; more decompositions exist.
