Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625040, here are decompositions:

  • 29 + 8625011 = 8625040
  • 41 + 8624999 = 8625040
  • 59 + 8624981 = 8625040
  • 167 + 8624873 = 8625040
  • 233 + 8624807 = 8625040
  • 269 + 8624771 = 8625040
  • 419 + 8624621 = 8625040
  • 467 + 8624573 = 8625040

Showing the first eight; more decompositions exist.
