Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671860, here are decompositions:

  • 23 + 8671837 = 8671860
  • 139 + 8671721 = 8671860
  • 149 + 8671711 = 8671860
  • 151 + 8671709 = 8671860
  • 163 + 8671697 = 8671860
  • 191 + 8671669 = 8671860
  • 227 + 8671633 = 8671860
  • 229 + 8671631 = 8671860

Showing the first eight; more decompositions exist.
