Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147496894, here are decompositions:

  • 31 + 2147496863 = 2147496894
  • 41 + 2147496853 = 2147496894
  • 47 + 2147496847 = 2147496894
  • 163 + 2147496731 = 2147496894
  • 181 + 2147496713 = 2147496894
  • 241 + 2147496653 = 2147496894
  • 271 + 2147496623 = 2147496894
  • 337 + 2147496557 = 2147496894

Showing the first eight; more decompositions exist.
