Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608224, here are decompositions:

7 + 31608217 = 31608224
61 + 31608163 = 31608224
157 + 31608067 = 31608224
163 + 31608061 = 31608224
211 + 31608013 = 31608224
367 + 31607857 = 31608224
433 + 31607791 = 31608224
541 + 31607683 = 31608224

Showing the first eight; more decompositions exist.
