Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85806, here are decompositions:

  • 13 + 85793 = 85806
  • 73 + 85733 = 85806
  • 89 + 85717 = 85806
  • 103 + 85703 = 85806
  • 137 + 85669 = 85806
  • 139 + 85667 = 85806
  • 163 + 85643 = 85806
  • 167 + 85639 = 85806

Showing the first eight; more decompositions exist.
