Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39908, here are decompositions:

  • 7 + 39901 = 39908
  • 31 + 39877 = 39908
  • 61 + 39847 = 39908
  • 67 + 39841 = 39908
  • 79 + 39829 = 39908
  • 109 + 39799 = 39908
  • 139 + 39769 = 39908
  • 181 + 39727 = 39908

Showing the first eight; more decompositions exist.
