Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39664, here are decompositions:

  • 5 + 39659 = 39664
  • 41 + 39623 = 39664
  • 83 + 39581 = 39664
  • 101 + 39563 = 39664
  • 113 + 39551 = 39664
  • 281 + 39383 = 39664
  • 293 + 39371 = 39664
  • 347 + 39317 = 39664

Showing the first eight; more decompositions exist.
