Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688860, here are decompositions:

  • 31 + 8688829 = 8688860
  • 43 + 8688817 = 8688860
  • 73 + 8688787 = 8688860
  • 157 + 8688703 = 8688860
  • 163 + 8688697 = 8688860
  • 277 + 8688583 = 8688860
  • 283 + 8688577 = 8688860
  • 307 + 8688553 = 8688860

Showing the first eight; more decompositions exist.
