Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498736, here are decompositions:

  • 7 + 2147498729 = 2147498736
  • 13 + 2147498723 = 2147498736
  • 59 + 2147498677 = 2147498736
  • 79 + 2147498657 = 2147498736
  • 83 + 2147498653 = 2147498736
  • 107 + 2147498629 = 2147498736
  • 109 + 2147498627 = 2147498736
  • 193 + 2147498543 = 2147498736

Showing the first eight; more decompositions exist.
