Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444706, here are decompositions:

  • 79 + 31444627 = 31444706
  • 229 + 31444477 = 31444706
  • 379 + 31444327 = 31444706
  • 457 + 31444249 = 31444706
  • 547 + 31444159 = 31444706
  • 619 + 31444087 = 31444706
  • 757 + 31443949 = 31444706
  • 823 + 31443883 = 31444706

Showing the first eight; more decompositions exist.
