Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688402, here are decompositions:

  • 5 + 8688397 = 8688402
  • 53 + 8688349 = 8688402
  • 103 + 8688299 = 8688402
  • 131 + 8688271 = 8688402
  • 181 + 8688221 = 8688402
  • 193 + 8688209 = 8688402
  • 199 + 8688203 = 8688402
  • 241 + 8688161 = 8688402

Showing the first eight; more decompositions exist.
