Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673540, here are decompositions:

  • 23 + 8673517 = 8673540
  • 41 + 8673499 = 8673540
  • 107 + 8673433 = 8673540
  • 151 + 8673389 = 8673540
  • 163 + 8673377 = 8673540
  • 167 + 8673373 = 8673540
  • 179 + 8673361 = 8673540
  • 181 + 8673359 = 8673540

Showing the first eight; more decompositions exist.
