Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593574, here are decompositions:

3 + 31593571 = 31593574
11 + 31593563 = 31593574
41 + 31593533 = 31593574
71 + 31593503 = 31593574
83 + 31593491 = 31593574
113 + 31593461 = 31593574
137 + 31593437 = 31593574
197 + 31593377 = 31593574

Showing the first eight; more decompositions exist.
