Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593016, here are decompositions:

5 + 31593011 = 31593016
23 + 31592993 = 31593016
167 + 31592849 = 31593016
173 + 31592843 = 31593016
269 + 31592747 = 31593016
353 + 31592663 = 31593016
449 + 31592567 = 31593016
563 + 31592453 = 31593016

Showing the first eight; more decompositions exist.
