Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593374, here are decompositions:

31 + 31593343 = 31593374
61 + 31593313 = 31593374
67 + 31593307 = 31593374
181 + 31593193 = 31593374
277 + 31593097 = 31593374
541 + 31592833 = 31593374
577 + 31592797 = 31593374
601 + 31592773 = 31593374

Showing the first eight; more decompositions exist.
