Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20016, here are decompositions:

  • 5 + 20011 = 20016
  • 19 + 19997 = 20016
  • 23 + 19993 = 20016
  • 37 + 19979 = 20016
  • 43 + 19973 = 20016
  • 53 + 19963 = 20016
  • 67 + 19949 = 20016
  • 79 + 19937 = 20016

Showing the first eight; more decompositions exist.
