Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593488, here are decompositions:

97 + 31593391 = 31593488
181 + 31593307 = 31593488
379 + 31593109 = 31593488
457 + 31593031 = 31593488
541 + 31592947 = 31593488
691 + 31592797 = 31593488
709 + 31592779 = 31593488
727 + 31592761 = 31593488

Showing the first eight; more decompositions exist.
