Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568224, here are decompositions:

3 + 31568221 = 31568224
101 + 31568123 = 31568224
137 + 31568087 = 31568224
197 + 31568027 = 31568224
263 + 31567961 = 31568224
293 + 31567931 = 31568224
587 + 31567637 = 31568224
773 + 31567451 = 31568224

Showing the first eight; more decompositions exist.
