Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404468, here are decompositions:

  • 29 + 2147404439 = 2147404468
  • 137 + 2147404331 = 2147404468
  • 149 + 2147404319 = 2147404468
  • 239 + 2147404229 = 2147404468
  • 257 + 2147404211 = 2147404468
  • 311 + 2147404157 = 2147404468
  • 347 + 2147404121 = 2147404468
  • 401 + 2147404067 = 2147404468

Showing the first eight; more decompositions exist.
