Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39666, here are decompositions:

  • 7 + 39659 = 39666
  • 43 + 39623 = 39666
  • 47 + 39619 = 39666
  • 59 + 39607 = 39666
  • 97 + 39569 = 39666
  • 103 + 39563 = 39666
  • 157 + 39509 = 39666
  • 163 + 39503 = 39666

Showing the first eight; more decompositions exist.
