Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497806, here are decompositions:

  • 37 + 2147497769 = 2147497806
  • 73 + 2147497733 = 2147497806
  • 89 + 2147497717 = 2147497806
  • 107 + 2147497699 = 2147497806
  • 109 + 2147497697 = 2147497806
  • 283 + 2147497523 = 2147497806
  • 313 + 2147497493 = 2147497806
  • 317 + 2147497489 = 2147497806

Showing the first eight; more decompositions exist.
