Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8904, here are decompositions:

  • 11 + 8893 = 8904
  • 17 + 8887 = 8904
  • 37 + 8867 = 8904
  • 41 + 8863 = 8904
  • 43 + 8861 = 8904
  • 67 + 8837 = 8904
  • 73 + 8831 = 8904
  • 83 + 8821 = 8904

Showing the first eight; more decompositions exist.
