Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1996, here are decompositions:

  • 3 + 1993 = 1996
  • 17 + 1979 = 1996
  • 23 + 1973 = 1996
  • 47 + 1949 = 1996
  • 83 + 1913 = 1996
  • 89 + 1907 = 1996
  • 107 + 1889 = 1996
  • 149 + 1847 = 1996

Showing the first eight; more decompositions exist.
