Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444750, here are decompositions:

  • 23 + 31444727 = 31444750
  • 59 + 31444691 = 31444750
  • 89 + 31444661 = 31444750
  • 101 + 31444649 = 31444750
  • 107 + 31444643 = 31444750
  • 191 + 31444559 = 31444750
  • 347 + 31444403 = 31444750
  • 383 + 31444367 = 31444750

Showing the first eight; more decompositions exist.
