Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2016, here are decompositions:

  • 5 + 2011 = 2016
  • 13 + 2003 = 2016
  • 17 + 1999 = 2016
  • 19 + 1997 = 2016
  • 23 + 1993 = 2016
  • 29 + 1987 = 2016
  • 37 + 1979 = 2016
  • 43 + 1973 = 2016

Showing the first eight; more decompositions exist.
