Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496224, here are decompositions:

3 + 31496221 = 31496224
5 + 31496219 = 31496224
83 + 31496141 = 31496224
101 + 31496123 = 31496224
167 + 31496057 = 31496224
197 + 31496027 = 31496224
467 + 31495757 = 31496224
491 + 31495733 = 31496224

Showing the first eight; more decompositions exist.
