Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497750, here are decompositions:

  • 17 + 2147497733 = 2147497750
  • 53 + 2147497697 = 2147497750
  • 59 + 2147497691 = 2147497750
  • 89 + 2147497661 = 2147497750
  • 179 + 2147497571 = 2147497750
  • 191 + 2147497559 = 2147497750
  • 227 + 2147497523 = 2147497750
  • 257 + 2147497493 = 2147497750

Showing the first eight; more decompositions exist.
