Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593630, here are decompositions:

17 + 31593613 = 31593630
23 + 31593607 = 31593630
41 + 31593589 = 31593630
59 + 31593571 = 31593630
67 + 31593563 = 31593630
97 + 31593533 = 31593630
113 + 31593517 = 31593630
127 + 31593503 = 31593630

Showing the first eight; more decompositions exist.
