Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2126, here are decompositions:

  • 13 + 2113 = 2126
  • 37 + 2089 = 2126
  • 43 + 2083 = 2126
  • 73 + 2053 = 2126
  • 97 + 2029 = 2126
  • 109 + 2017 = 2126
  • 127 + 1999 = 2126
  • 139 + 1987 = 2126

Showing the first eight; more decompositions exist.
