Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483766, here are decompositions:

7 + 31483759 = 31483766
43 + 31483723 = 31483766
103 + 31483663 = 31483766
313 + 31483453 = 31483766
337 + 31483429 = 31483766
397 + 31483369 = 31483766
439 + 31483327 = 31483766
673 + 31483093 = 31483766

Showing the first eight; more decompositions exist.
