Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147539694, here are decompositions:

  • 7 + 2147539687 = 2147539694
  • 73 + 2147539621 = 2147539694
  • 127 + 2147539567 = 2147539694
  • 163 + 2147539531 = 2147539694
  • 241 + 2147539453 = 2147539694
  • 373 + 2147539321 = 2147539694
  • 661 + 2147539033 = 2147539694
  • 787 + 2147538907 = 2147539694

Showing the first eight; more decompositions exist.
