Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483372, here are decompositions:

3 + 31483369 = 31483372
59 + 31483313 = 31483372
311 + 31483061 = 31483372
593 + 31482779 = 31483372
773 + 31482599 = 31483372
821 + 31482551 = 31483372
863 + 31482509 = 31483372
971 + 31482401 = 31483372

Showing the first eight; more decompositions exist.
