Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404426, here are decompositions:

  • 107 + 2147404319 = 2147404426
  • 179 + 2147404247 = 2147404426
  • 197 + 2147404229 = 2147404426
  • 269 + 2147404157 = 2147404426
  • 359 + 2147404067 = 2147404426
  • 389 + 2147404037 = 2147404426
  • 443 + 2147403983 = 2147404426
  • 569 + 2147403857 = 2147404426

Showing the first eight; more decompositions exist.
