Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404156, here are decompositions:

  • 3 + 2147404153 = 2147404156
  • 89 + 2147404067 = 2147404156
  • 137 + 2147404019 = 2147404156
  • 173 + 2147403983 = 2147404156
  • 263 + 2147403893 = 2147404156
  • 269 + 2147403887 = 2147404156
  • 419 + 2147403737 = 2147404156
  • 563 + 2147403593 = 2147404156

Showing the first eight; more decompositions exist.
