Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452744, here are decompositions:

  • 5 + 31452739 = 31452744
  • 13 + 31452731 = 31452744
  • 17 + 31452727 = 31452744
  • 23 + 31452721 = 31452744
  • 61 + 31452683 = 31452744
  • 67 + 31452677 = 31452744
  • 137 + 31452607 = 31452744
  • 157 + 31452587 = 31452744

Showing the first eight; more decompositions exist.
