Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449692, here are decompositions:

  • 3 + 31449689 = 31449692
  • 13 + 31449679 = 31449692
  • 19 + 31449673 = 31449692
  • 73 + 31449619 = 31449692
  • 103 + 31449589 = 31449692
  • 139 + 31449553 = 31449692
  • 193 + 31449499 = 31449692
  • 199 + 31449493 = 31449692

Showing the first eight; more decompositions exist.
