Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681874, here are decompositions:

  • 17 + 8681857 = 8681874
  • 23 + 8681851 = 8681874
  • 37 + 8681837 = 8681874
  • 43 + 8681831 = 8681874
  • 53 + 8681821 = 8681874
  • 137 + 8681737 = 8681874
  • 167 + 8681707 = 8681874
  • 181 + 8681693 = 8681874

Showing the first eight; more decompositions exist.
