Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622864, here are decompositions:

  • 61 + 31622803 = 31622864
  • 151 + 31622713 = 31622864
  • 181 + 31622683 = 31622864
  • 193 + 31622671 = 31622864
  • 223 + 31622641 = 31622864
  • 373 + 31622491 = 31622864
  • 397 + 31622467 = 31622864
  • 487 + 31622377 = 31622864

Showing the first eight; more decompositions exist.
