Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671856, here are decompositions:

  • 19 + 8671837 = 8671856
  • 223 + 8671633 = 8671856
  • 283 + 8671573 = 8671856
  • 307 + 8671549 = 8671856
  • 337 + 8671519 = 8671856
  • 409 + 8671447 = 8671856
  • 463 + 8671393 = 8671856
  • 607 + 8671249 = 8671856

Showing the first eight; more decompositions exist.
