Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593532, here are decompositions:

29 + 31593503 = 31593532
41 + 31593491 = 31593532
53 + 31593479 = 31593532
71 + 31593461 = 31593532
233 + 31593299 = 31593532
281 + 31593251 = 31593532
359 + 31593173 = 31593532
521 + 31593011 = 31593532

Showing the first eight; more decompositions exist.
