Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404218, here are decompositions:

  • 7 + 2147404211 = 2147404218
  • 61 + 2147404157 = 2147404218
  • 97 + 2147404121 = 2147404218
  • 151 + 2147404067 = 2147404218
  • 181 + 2147404037 = 2147404218
  • 199 + 2147404019 = 2147404218
  • 331 + 2147403887 = 2147404218
  • 359 + 2147403859 = 2147404218

Showing the first eight; more decompositions exist.
