Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404874, here are decompositions:

  • 103 + 2147404771 = 2147404874
  • 163 + 2147404711 = 2147404874
  • 547 + 2147404327 = 2147404874
  • 631 + 2147404243 = 2147404874
  • 691 + 2147404183 = 2147404874
  • 733 + 2147404141 = 2147404874
  • 1093 + 2147403781 = 2147404874
  • 1201 + 2147403673 = 2147404874

Showing the first eight; more decompositions exist.
