Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688986, here are decompositions:

  • 43 + 8688943 = 8688986
  • 67 + 8688919 = 8688986
  • 157 + 8688829 = 8688986
  • 199 + 8688787 = 8688986
  • 283 + 8688703 = 8688986
  • 373 + 8688613 = 8688986
  • 379 + 8688607 = 8688986
  • 409 + 8688577 = 8688986

Showing the first eight; more decompositions exist.
