Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20106, here are decompositions:

  • 5 + 20101 = 20106
  • 17 + 20089 = 20106
  • 43 + 20063 = 20106
  • 59 + 20047 = 20106
  • 83 + 20023 = 20106
  • 109 + 19997 = 20106
  • 113 + 19993 = 20106
  • 127 + 19979 = 20106

Showing the first eight; more decompositions exist.
