Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593928, here are decompositions:

59 + 31593869 = 31593928
89 + 31593839 = 31593928
131 + 31593797 = 31593928
239 + 31593689 = 31593928
281 + 31593647 = 31593928
449 + 31593479 = 31593928
467 + 31593461 = 31593928
491 + 31593437 = 31593928

Showing the first eight; more decompositions exist.
