Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483432, here are decompositions:

3 + 31483429 = 31483432
41 + 31483391 = 31483432
263 + 31483169 = 31483432
269 + 31483163 = 31483432
593 + 31482839 = 31483432
599 + 31482833 = 31483432
653 + 31482779 = 31483432
863 + 31482569 = 31483432

Showing the first eight; more decompositions exist.
