Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593370, here are decompositions:

  • 71 + 31593299 = 31593370
  • 173 + 31593197 = 31593370
  • 197 + 31593173 = 31593370
  • 359 + 31593011 = 31593370
  • 449 + 31592921 = 31593370
  • 521 + 31592849 = 31593370
  • 719 + 31592651 = 31593370
  • 839 + 31592531 = 31593370

Showing the first eight; more decompositions exist.
