Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147540662, here are decompositions:

  • 101 + 2147540561 = 2147540662
  • 191 + 2147540471 = 2147540662
  • 263 + 2147540399 = 2147540662
  • 383 + 2147540279 = 2147540662
  • 461 + 2147540201 = 2147540662
  • 599 + 2147540063 = 2147540662
  • 863 + 2147539799 = 2147540662
  • 1031 + 2147539631 = 2147540662

Showing the first eight; more decompositions exist.
