Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 888, here are decompositions:

  • 5 + 883 = 888
  • 7 + 881 = 888
  • 11 + 877 = 888
  • 29 + 859 = 888
  • 31 + 857 = 888
  • 59 + 829 = 888
  • 61 + 827 = 888
  • 67 + 821 = 888

Showing the first eight; more decompositions exist.
