Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2000, here are decompositions:

  • 3 + 1997 = 2000
  • 7 + 1993 = 2000
  • 13 + 1987 = 2000
  • 67 + 1933 = 2000
  • 127 + 1873 = 2000
  • 139 + 1861 = 2000
  • 199 + 1801 = 2000
  • 211 + 1789 = 2000

Showing the first eight; more decompositions exist.
