Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671432, here are decompositions:

  • 5 + 8671427 = 8671432
  • 23 + 8671409 = 8671432
  • 71 + 8671361 = 8671432
  • 101 + 8671331 = 8671432
  • 239 + 8671193 = 8671432
  • 281 + 8671151 = 8671432
  • 401 + 8671031 = 8671432
  • 443 + 8670989 = 8671432

Showing the first eight; more decompositions exist.
