Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499806, here are decompositions:

  • 79 + 2147499727 = 2147499806
  • 103 + 2147499703 = 2147499806
  • 229 + 2147499577 = 2147499806
  • 349 + 2147499457 = 2147499806
  • 373 + 2147499433 = 2147499806
  • 457 + 2147499349 = 2147499806
  • 523 + 2147499283 = 2147499806
  • 769 + 2147499037 = 2147499806

Showing the first eight; more decompositions exist.
