Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599224, here are decompositions:

31 + 31599193 = 31599224
67 + 31599157 = 31599224
271 + 31598953 = 31599224
277 + 31598947 = 31599224
313 + 31598911 = 31599224
337 + 31598887 = 31599224
367 + 31598857 = 31599224
523 + 31598701 = 31599224

Showing the first eight; more decompositions exist.
