Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672278, here are decompositions:

  • 5 + 8672273 = 8672278
  • 11 + 8672267 = 8672278
  • 71 + 8672207 = 8672278
  • 101 + 8672177 = 8672278
  • 179 + 8672099 = 8672278
  • 191 + 8672087 = 8672278
  • 311 + 8671967 = 8672278
  • 359 + 8671919 = 8672278

Showing the first eight; more decompositions exist.
