Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2106, here are decompositions:

  • 7 + 2099 = 2106
  • 17 + 2089 = 2106
  • 19 + 2087 = 2106
  • 23 + 2083 = 2106
  • 37 + 2069 = 2106
  • 43 + 2063 = 2106
  • 53 + 2053 = 2106
  • 67 + 2039 = 2106

Showing the first eight; more decompositions exist.
