Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593460, here are decompositions:

23 + 31593437 = 31593460
71 + 31593389 = 31593460
83 + 31593377 = 31593460
263 + 31593197 = 31593460
449 + 31593011 = 31593460
467 + 31592993 = 31593460
617 + 31592843 = 31593460
797 + 31592663 = 31593460

Showing the first eight; more decompositions exist.
