Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39744, here are decompositions:

  • 11 + 39733 = 39744
  • 17 + 39727 = 39744
  • 41 + 39703 = 39744
  • 73 + 39671 = 39744
  • 113 + 39631 = 39744
  • 137 + 39607 = 39744
  • 163 + 39581 = 39744
  • 181 + 39563 = 39744

Showing the first eight; more decompositions exist.
