Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497870, here are decompositions:

  • 101 + 2147497769 = 2147497870
  • 113 + 2147497757 = 2147497870
  • 137 + 2147497733 = 2147497870
  • 173 + 2147497697 = 2147497870
  • 179 + 2147497691 = 2147497870
  • 311 + 2147497559 = 2147497870
  • 347 + 2147497523 = 2147497870
  • 389 + 2147497481 = 2147497870

Showing the first eight; more decompositions exist.
