Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593580, here are decompositions:

17 + 31593563 = 31593580
47 + 31593533 = 31593580
89 + 31593491 = 31593580
101 + 31593479 = 31593580
191 + 31593389 = 31593580
281 + 31593299 = 31593580
383 + 31593197 = 31593580
569 + 31593011 = 31593580

Showing the first eight; more decompositions exist.
