Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720084, here are decompositions:

  • 3 + 8720081 = 8720084
  • 13 + 8720071 = 8720084
  • 97 + 8719987 = 8720084
  • 181 + 8719903 = 8720084
  • 211 + 8719873 = 8720084
  • 271 + 8719813 = 8720084
  • 283 + 8719801 = 8720084
  • 313 + 8719771 = 8720084

Showing the first eight; more decompositions exist.
