Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147376386, here are decompositions:

  • 7 + 2147376379 = 2147376386
  • 19 + 2147376367 = 2147376386
  • 193 + 2147376193 = 2147376386
  • 313 + 2147376073 = 2147376386
  • 487 + 2147375899 = 2147376386
  • 613 + 2147375773 = 2147376386
  • 709 + 2147375677 = 2147376386
  • 877 + 2147375509 = 2147376386

Showing the first eight; more decompositions exist.
