Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539834, here are decompositions:

  • 13 + 31539821 = 31539834
  • 17 + 31539817 = 31539834
  • 71 + 31539763 = 31539834
  • 97 + 31539737 = 31539834
  • 107 + 31539727 = 31539834
  • 127 + 31539707 = 31539834
  • 163 + 31539671 = 31539834
  • 173 + 31539661 = 31539834

Showing the first eight; more decompositions exist.
