Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599744, here are decompositions:

  • 17 + 31599727 = 31599744
  • 37 + 31599707 = 31599744
  • 41 + 31599703 = 31599744
  • 61 + 31599683 = 31599744
  • 73 + 31599671 = 31599744
  • 181 + 31599563 = 31599744
  • 191 + 31599553 = 31599744
  • 193 + 31599551 = 31599744

Showing the first eight; more decompositions exist.
