Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671730, here are decompositions:

  • 19 + 8671711 = 8671730
  • 61 + 8671669 = 8671730
  • 97 + 8671633 = 8671730
  • 157 + 8671573 = 8671730
  • 181 + 8671549 = 8671730
  • 211 + 8671519 = 8671730
  • 229 + 8671501 = 8671730
  • 283 + 8671447 = 8671730

Showing the first eight; more decompositions exist.
