Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19964, here are decompositions:

  • 3 + 19961 = 19964
  • 37 + 19927 = 19964
  • 73 + 19891 = 19964
  • 97 + 19867 = 19964
  • 103 + 19861 = 19964
  • 151 + 19813 = 19964
  • 163 + 19801 = 19964
  • 211 + 19753 = 19964

Showing the first eight; more decompositions exist.
