Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688870, here are decompositions:

  • 7 + 8688863 = 8688870
  • 41 + 8688829 = 8688870
  • 53 + 8688817 = 8688870
  • 61 + 8688809 = 8688870
  • 79 + 8688791 = 8688870
  • 83 + 8688787 = 8688870
  • 131 + 8688739 = 8688870
  • 163 + 8688707 = 8688870

Showing the first eight; more decompositions exist.
