Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39888, here are decompositions:

  • 5 + 39883 = 39888
  • 11 + 39877 = 39888
  • 19 + 39869 = 39888
  • 31 + 39857 = 39888
  • 41 + 39847 = 39888
  • 47 + 39841 = 39888
  • 59 + 39829 = 39888
  • 61 + 39827 = 39888

Showing the first eight; more decompositions exist.
