Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472682, here are decompositions:

  • 23 + 2147472659 = 2147472682
  • 71 + 2147472611 = 2147472682
  • 191 + 2147472491 = 2147472682
  • 233 + 2147472449 = 2147472682
  • 239 + 2147472443 = 2147472682
  • 269 + 2147472413 = 2147472682
  • 419 + 2147472263 = 2147472682
  • 431 + 2147472251 = 2147472682

Showing the first eight; more decompositions exist.
