Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518694, here are decompositions:

  • 3 + 31518691 = 31518694
  • 17 + 31518677 = 31518694
  • 41 + 31518653 = 31518694
  • 47 + 31518647 = 31518694
  • 101 + 31518593 = 31518694
  • 173 + 31518521 = 31518694
  • 227 + 31518467 = 31518694
  • 521 + 31518173 = 31518694

Showing the first eight; more decompositions exist.
