Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483042, here are decompositions:

263 + 31482779 = 31483042
281 + 31482761 = 31483042
359 + 31482683 = 31483042
401 + 31482641 = 31483042
443 + 31482599 = 31483042
491 + 31482551 = 31483042
641 + 31482401 = 31483042
653 + 31482389 = 31483042

Showing the first eight; more decompositions exist.
