Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483710, here are decompositions:

19 + 31483691 = 31483710
47 + 31483663 = 31483710
61 + 31483649 = 31483710
113 + 31483597 = 31483710
127 + 31483583 = 31483710
157 + 31483553 = 31483710
163 + 31483547 = 31483710
239 + 31483471 = 31483710

Showing the first eight; more decompositions exist.
