Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588704, here are decompositions:

  • 5 + 31588699 = 31588704
  • 11 + 31588693 = 31588704
  • 31 + 31588673 = 31588704
  • 47 + 31588657 = 31588704
  • 61 + 31588643 = 31588704
  • 73 + 31588631 = 31588704
  • 97 + 31588607 = 31588704
  • 101 + 31588603 = 31588704

Showing the first eight; more decompositions exist.
