Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688872, here are decompositions:

  • 43 + 8688829 = 8688872
  • 271 + 8688601 = 8688872
  • 463 + 8688409 = 8688872
  • 523 + 8688349 = 8688872
  • 601 + 8688271 = 8688872
  • 613 + 8688259 = 8688872
  • 739 + 8688133 = 8688872
  • 859 + 8688013 = 8688872

Showing the first eight; more decompositions exist.
