Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490662, here are decompositions:

  • 3 + 31490659 = 31490662
  • 11 + 31490651 = 31490662
  • 29 + 31490633 = 31490662
  • 41 + 31490621 = 31490662
  • 53 + 31490609 = 31490662
  • 89 + 31490573 = 31490662
  • 173 + 31490489 = 31490662
  • 263 + 31490399 = 31490662

Showing the first eight; more decompositions exist.
