Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519632, here are decompositions:

  • 31 + 31519601 = 31519632
  • 61 + 31519571 = 31519632
  • 101 + 31519531 = 31519632
  • 113 + 31519519 = 31519632
  • 149 + 31519483 = 31519632
  • 173 + 31519459 = 31519632
  • 191 + 31519441 = 31519632
  • 229 + 31519403 = 31519632

Showing the first eight; more decompositions exist.
