Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471706, here are decompositions:

  • 3 + 31471703 = 31471706
  • 43 + 31471663 = 31471706
  • 67 + 31471639 = 31471706
  • 73 + 31471633 = 31471706
  • 127 + 31471579 = 31471706
  • 157 + 31471549 = 31471706
  • 349 + 31471357 = 31471706
  • 499 + 31471207 = 31471706

Showing the first eight; more decompositions exist.
