Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526664, here are decompositions:

  • 17 + 31526647 = 31526664
  • 31 + 31526633 = 31526664
  • 47 + 31526617 = 31526664
  • 61 + 31526603 = 31526664
  • 101 + 31526563 = 31526664
  • 131 + 31526533 = 31526664
  • 137 + 31526527 = 31526664
  • 167 + 31526497 = 31526664

Showing the first eight; more decompositions exist.
