Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497834, here are decompositions:

  • 101 + 2147497733 = 2147497834
  • 137 + 2147497697 = 2147497834
  • 173 + 2147497661 = 2147497834
  • 263 + 2147497571 = 2147497834
  • 311 + 2147497523 = 2147497834
  • 353 + 2147497481 = 2147497834
  • 431 + 2147497403 = 2147497834
  • 701 + 2147497133 = 2147497834

Showing the first eight; more decompositions exist.
