Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593862, here are decompositions:

23 + 31593839 = 31593862
29 + 31593833 = 31593862
173 + 31593689 = 31593862
233 + 31593629 = 31593862
359 + 31593503 = 31593862
383 + 31593479 = 31593862
401 + 31593461 = 31593862
563 + 31593299 = 31593862

Showing the first eight; more decompositions exist.
