Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65940, here are decompositions:

  • 11 + 65929 = 65940
  • 13 + 65927 = 65940
  • 19 + 65921 = 65940
  • 41 + 65899 = 65940
  • 59 + 65881 = 65940
  • 73 + 65867 = 65940
  • 89 + 65851 = 65940
  • 97 + 65843 = 65940

Showing the first eight; more decompositions exist.
