Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404078, here are decompositions:

  • 11 + 2147404067 = 2147404078
  • 41 + 2147404037 = 2147404078
  • 47 + 2147404031 = 2147404078
  • 59 + 2147404019 = 2147404078
  • 191 + 2147403887 = 2147404078
  • 359 + 2147403719 = 2147404078
  • 569 + 2147403509 = 2147404078
  • 1151 + 2147402927 = 2147404078

Showing the first eight; more decompositions exist.
