Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483072, here are decompositions:

3 + 31483069 = 31483072
11 + 31483061 = 31483072
233 + 31482839 = 31483072
239 + 31482833 = 31483072
251 + 31482821 = 31483072
293 + 31482779 = 31483072
311 + 31482761 = 31483072
389 + 31482683 = 31483072

Showing the first eight; more decompositions exist.
