Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625320, here are decompositions:

  • 3 + 8625317 = 8625320
  • 7 + 8625313 = 8625320
  • 19 + 8625301 = 8625320
  • 31 + 8625289 = 8625320
  • 73 + 8625247 = 8625320
  • 199 + 8625121 = 8625320
  • 229 + 8625091 = 8625320
  • 307 + 8625013 = 8625320

Showing the first eight; more decompositions exist.
