Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497876, here are decompositions:

  • 107 + 2147497769 = 2147497876
  • 179 + 2147497697 = 2147497876
  • 317 + 2147497559 = 2147497876
  • 353 + 2147497523 = 2147497876
  • 383 + 2147497493 = 2147497876
  • 743 + 2147497133 = 2147497876
  • 857 + 2147497019 = 2147497876
  • 1013 + 2147496863 = 2147497876

Showing the first eight; more decompositions exist.
