Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622666, here are decompositions:

  • 3 + 31622663 = 31622666
  • 37 + 31622629 = 31622666
  • 67 + 31622599 = 31622666
  • 157 + 31622509 = 31622666
  • 193 + 31622473 = 31622666
  • 199 + 31622467 = 31622666
  • 277 + 31622389 = 31622666
  • 373 + 31622293 = 31622666

Showing the first eight; more decompositions exist.
