Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593566, here are decompositions:

3 + 31593563 = 31593566
13 + 31593553 = 31593566
223 + 31593343 = 31593566
313 + 31593253 = 31593566
373 + 31593193 = 31593566
457 + 31593109 = 31593566
607 + 31592959 = 31593566
619 + 31592947 = 31593566

Showing the first eight; more decompositions exist.
