Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688850, here are decompositions:

  • 41 + 8688809 = 8688850
  • 59 + 8688791 = 8688850
  • 179 + 8688671 = 8688850
  • 239 + 8688611 = 8688850
  • 257 + 8688593 = 8688850
  • 281 + 8688569 = 8688850
  • 293 + 8688557 = 8688850
  • 353 + 8688497 = 8688850

Showing the first eight; more decompositions exist.
