Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483982, here are decompositions:

3 + 31483979 = 31483982
163 + 31483819 = 31483982
181 + 31483801 = 31483982
193 + 31483789 = 31483982
223 + 31483759 = 31483982
433 + 31483549 = 31483982
613 + 31483369 = 31483982
631 + 31483351 = 31483982

Showing the first eight; more decompositions exist.
