Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483746, here are decompositions:

13 + 31483733 = 31483746
23 + 31483723 = 31483746
83 + 31483663 = 31483746
97 + 31483649 = 31483746
149 + 31483597 = 31483746
163 + 31483583 = 31483746
193 + 31483553 = 31483746
197 + 31483549 = 31483746

Showing the first eight; more decompositions exist.
