Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703280, here are decompositions:

  • 23 + 8703257 = 8703280
  • 107 + 8703173 = 8703280
  • 167 + 8703113 = 8703280
  • 191 + 8703089 = 8703280
  • 233 + 8703047 = 8703280
  • 239 + 8703041 = 8703280
  • 281 + 8702999 = 8703280
  • 401 + 8702879 = 8703280

Showing the first eight; more decompositions exist.
