Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620834, here are decompositions:

  • 13 + 31620821 = 31620834
  • 41 + 31620793 = 31620834
  • 71 + 31620763 = 31620834
  • 83 + 31620751 = 31620834
  • 97 + 31620737 = 31620834
  • 101 + 31620733 = 31620834
  • 151 + 31620683 = 31620834
  • 173 + 31620661 = 31620834

Showing the first eight; more decompositions exist.
