Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725408, here are decompositions:

  • 11 + 8725397 = 8725408
  • 17 + 8725391 = 8725408
  • 47 + 8725361 = 8725408
  • 89 + 8725319 = 8725408
  • 101 + 8725307 = 8725408
  • 191 + 8725217 = 8725408
  • 269 + 8725139 = 8725408
  • 317 + 8725091 = 8725408

Showing the first eight; more decompositions exist.
