Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483012, here are decompositions:

173 + 31482839 = 31483012
179 + 31482833 = 31483012
191 + 31482821 = 31483012
233 + 31482779 = 31483012
251 + 31482761 = 31483012
269 + 31482743 = 31483012
443 + 31482569 = 31483012
461 + 31482551 = 31483012

Showing the first eight; more decompositions exist.
