Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483212, here are decompositions:

43 + 31483169 = 31483212
151 + 31483061 = 31483212
239 + 31482973 = 31483212
353 + 31482859 = 31483212
373 + 31482839 = 31483212
379 + 31482833 = 31483212
389 + 31482823 = 31483212
433 + 31482779 = 31483212

Showing the first eight; more decompositions exist.
