Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2002, here are decompositions:

  • 3 + 1999 = 2002
  • 5 + 1997 = 2002
  • 23 + 1979 = 2002
  • 29 + 1973 = 2002
  • 53 + 1949 = 2002
  • 71 + 1931 = 2002
  • 89 + 1913 = 2002
  • 101 + 1901 = 2002

Showing the first eight; more decompositions exist.
