Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39806, here are decompositions:

  • 7 + 39799 = 39806
  • 37 + 39769 = 39806
  • 73 + 39733 = 39806
  • 79 + 39727 = 39806
  • 97 + 39709 = 39806
  • 103 + 39703 = 39806
  • 127 + 39679 = 39806
  • 139 + 39667 = 39806

Showing the first eight; more decompositions exist.
