Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688646, here are decompositions:

  • 17 + 8688629 = 8688646
  • 53 + 8688593 = 8688646
  • 89 + 8688557 = 8688646
  • 149 + 8688497 = 8688646
  • 293 + 8688353 = 8688646
  • 347 + 8688299 = 8688646
  • 359 + 8688287 = 8688646
  • 443 + 8688203 = 8688646

Showing the first eight; more decompositions exist.
