Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20706, here are decompositions:

  • 13 + 20693 = 20706
  • 43 + 20663 = 20706
  • 67 + 20639 = 20706
  • 79 + 20627 = 20706
  • 107 + 20599 = 20706
  • 113 + 20593 = 20706
  • 157 + 20549 = 20706
  • 163 + 20543 = 20706

Showing the first eight; more decompositions exist.
