Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612874, here are decompositions:

  • 43 + 31612831 = 31612874
  • 127 + 31612747 = 31612874
  • 211 + 31612663 = 31612874
  • 277 + 31612597 = 31612874
  • 421 + 31612453 = 31612874
  • 523 + 31612351 = 31612874
  • 673 + 31612201 = 31612874
  • 877 + 31611997 = 31612874

Showing the first eight; more decompositions exist.
