Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697280, here are decompositions:

  • 3 + 8697277 = 8697280
  • 17 + 8697263 = 8697280
  • 41 + 8697239 = 8697280
  • 47 + 8697233 = 8697280
  • 167 + 8697113 = 8697280
  • 173 + 8697107 = 8697280
  • 191 + 8697089 = 8697280
  • 281 + 8696999 = 8697280

Showing the first eight; more decompositions exist.
