Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593864, here are decompositions:

  • 31 + 31593833 = 31593864
  • 67 + 31593797 = 31593864
  • 97 + 31593767 = 31593864
  • 101 + 31593763 = 31593864
  • 223 + 31593641 = 31593864
  • 233 + 31593631 = 31593864
  • 251 + 31593613 = 31593864
  • 257 + 31593607 = 31593864

Showing the first eight; more decompositions exist.
