Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593224, here are decompositions:

31 + 31593193 = 31593224
127 + 31593097 = 31593224
193 + 31593031 = 31593224
241 + 31592983 = 31593224
277 + 31592947 = 31593224
463 + 31592761 = 31593224
541 + 31592683 = 31593224
547 + 31592677 = 31593224

Showing the first eight; more decompositions exist.
