Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295072720, here are decompositions:

  • 7 + 4295072713 = 4295072720
  • 31 + 4295072689 = 4295072720
  • 109 + 4295072611 = 4295072720
  • 283 + 4295072437 = 4295072720
  • 457 + 4295072263 = 4295072720
  • 571 + 4295072149 = 4295072720
  • 619 + 4295072101 = 4295072720
  • 709 + 4295072011 = 4295072720

Showing the first eight; more decompositions exist.
