Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469970, here are decompositions:

  • 53 + 2147469917 = 2147469970
  • 89 + 2147469881 = 2147469970
  • 311 + 2147469659 = 2147469970
  • 449 + 2147469521 = 2147469970
  • 479 + 2147469491 = 2147469970
  • 521 + 2147469449 = 2147469970
  • 641 + 2147469329 = 2147469970
  • 797 + 2147469173 = 2147469970

Showing the first eight; more decompositions exist.
