Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686842, here are decompositions:

  • 13 + 8686829 = 8686842
  • 113 + 8686729 = 8686842
  • 139 + 8686703 = 8686842
  • 163 + 8686679 = 8686842
  • 173 + 8686669 = 8686842
  • 181 + 8686661 = 8686842
  • 191 + 8686651 = 8686842
  • 313 + 8686529 = 8686842

Showing the first eight; more decompositions exist.
