Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39600, here are decompositions:

  • 19 + 39581 = 39600
  • 31 + 39569 = 39600
  • 37 + 39563 = 39600
  • 59 + 39541 = 39600
  • 79 + 39521 = 39600
  • 89 + 39511 = 39600
  • 97 + 39503 = 39600
  • 101 + 39499 = 39600

Showing the first eight; more decompositions exist.
