Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147568266, here are decompositions:

  • 73 + 2147568193 = 2147568266
  • 139 + 2147568127 = 2147568266
  • 163 + 2147568103 = 2147568266
  • 199 + 2147568067 = 2147568266
  • 379 + 2147567887 = 2147568266
  • 499 + 2147567767 = 2147568266
  • 577 + 2147567689 = 2147568266
  • 673 + 2147567593 = 2147568266

Showing the first eight; more decompositions exist.
