Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147495664, here are decompositions:

  • 37 + 2147495627 = 2147495664
  • 53 + 2147495611 = 2147495664
  • 103 + 2147495561 = 2147495664
  • 263 + 2147495401 = 2147495664
  • 283 + 2147495381 = 2147495664
  • 311 + 2147495353 = 2147495664
  • 317 + 2147495347 = 2147495664
  • 373 + 2147495291 = 2147495664

Showing the first eight; more decompositions exist.
