Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9000, here are decompositions:

  • 29 + 8971 = 9000
  • 31 + 8969 = 9000
  • 37 + 8963 = 9000
  • 59 + 8941 = 9000
  • 67 + 8933 = 9000
  • 71 + 8929 = 9000
  • 107 + 8893 = 9000
  • 113 + 8887 = 9000

Showing the first eight; more decompositions exist.
