Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483770, here are decompositions:

11 + 31483759 = 31483770
37 + 31483733 = 31483770
47 + 31483723 = 31483770
79 + 31483691 = 31483770
107 + 31483663 = 31483770
173 + 31483597 = 31483770
193 + 31483577 = 31483770
223 + 31483547 = 31483770

Showing the first eight; more decompositions exist.
