Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593562, here are decompositions:

29 + 31593533 = 31593562
59 + 31593503 = 31593562
71 + 31593491 = 31593562
83 + 31593479 = 31593562
101 + 31593461 = 31593562
173 + 31593389 = 31593562
263 + 31593299 = 31593562
311 + 31593251 = 31593562

Showing the first eight; more decompositions exist.
