Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591980, here are decompositions:

  • 17 + 8591963 = 8591980
  • 53 + 8591927 = 8591980
  • 71 + 8591909 = 8591980
  • 149 + 8591831 = 8591980
  • 167 + 8591813 = 8591980
  • 233 + 8591747 = 8591980
  • 263 + 8591717 = 8591980
  • 269 + 8591711 = 8591980

Showing the first eight; more decompositions exist.
