Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496386, here are decompositions:

17 + 31496369 = 31496386
167 + 31496219 = 31496386
263 + 31496123 = 31496386
359 + 31496027 = 31496386
653 + 31495733 = 31496386
797 + 31495589 = 31496386
863 + 31495523 = 31496386
983 + 31495403 = 31496386

Showing the first eight; more decompositions exist.
