Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593604, here are decompositions:

41 + 31593563 = 31593604
71 + 31593533 = 31593604
101 + 31593503 = 31593604
113 + 31593491 = 31593604
167 + 31593437 = 31593604
227 + 31593377 = 31593604
353 + 31593251 = 31593604
431 + 31593173 = 31593604

Showing the first eight; more decompositions exist.
