Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483742, here are decompositions:

19 + 31483723 = 31483742
79 + 31483663 = 31483742
193 + 31483549 = 31483742
271 + 31483471 = 31483742
313 + 31483429 = 31483742
373 + 31483369 = 31483742
673 + 31483069 = 31483742
691 + 31483051 = 31483742

Showing the first eight; more decompositions exist.
