Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2112, here are decompositions:

  • 13 + 2099 = 2112
  • 23 + 2089 = 2112
  • 29 + 2083 = 2112
  • 31 + 2081 = 2112
  • 43 + 2069 = 2112
  • 59 + 2053 = 2112
  • 73 + 2039 = 2112
  • 83 + 2029 = 2112

Showing the first eight; more decompositions exist.
