Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147459806, here are decompositions:

  • 53 + 2147459753 = 2147459806
  • 83 + 2147459723 = 2147459806
  • 227 + 2147459579 = 2147459806
  • 263 + 2147459543 = 2147459806
  • 269 + 2147459537 = 2147459806
  • 419 + 2147459387 = 2147459806
  • 449 + 2147459357 = 2147459806
  • 467 + 2147459339 = 2147459806

Showing the first eight; more decompositions exist.
