Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404892, here are decompositions:

  • 181 + 2147404711 = 2147404892
  • 271 + 2147404621 = 2147404892
  • 313 + 2147404579 = 2147404892
  • 463 + 2147404429 = 2147404892
  • 499 + 2147404393 = 2147404892
  • 709 + 2147404183 = 2147404892
  • 739 + 2147404153 = 2147404892
  • 751 + 2147404141 = 2147404892

Showing the first eight; more decompositions exist.
