Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499870, here are decompositions:

  • 7 + 2147499863 = 2147499870
  • 29 + 2147499841 = 2147499870
  • 41 + 2147499829 = 2147499870
  • 163 + 2147499707 = 2147499870
  • 167 + 2147499703 = 2147499870
  • 199 + 2147499671 = 2147499870
  • 293 + 2147499577 = 2147499870
  • 331 + 2147499539 = 2147499870

Showing the first eight; more decompositions exist.
