Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526814, here are decompositions:

  • 5 + 31526809 = 31526814
  • 23 + 31526791 = 31526814
  • 37 + 31526777 = 31526814
  • 41 + 31526773 = 31526814
  • 43 + 31526771 = 31526814
  • 61 + 31526753 = 31526814
  • 83 + 31526731 = 31526814
  • 101 + 31526713 = 31526814

Showing the first eight; more decompositions exist.
