Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 886, here are decompositions:

  • 3 + 883 = 886
  • 5 + 881 = 886
  • 23 + 863 = 886
  • 29 + 857 = 886
  • 47 + 839 = 886
  • 59 + 827 = 886
  • 89 + 797 = 886
  • 113 + 773 = 886

Showing the first eight; more decompositions exist.
