Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593558, here are decompositions:

5 + 31593553 = 31593558
41 + 31593517 = 31593558
47 + 31593511 = 31593558
67 + 31593491 = 31593558
79 + 31593479 = 31593558
97 + 31593461 = 31593558
167 + 31593391 = 31593558
181 + 31593377 = 31593558

Showing the first eight; more decompositions exist.
