Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483794, here are decompositions:

5 + 31483789 = 31483794
61 + 31483733 = 31483794
71 + 31483723 = 31483794
103 + 31483691 = 31483794
131 + 31483663 = 31483794
197 + 31483597 = 31483794
211 + 31483583 = 31483794
241 + 31483553 = 31483794

Showing the first eight; more decompositions exist.
