Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625290, here are decompositions:

  • 43 + 8625247 = 8625290
  • 61 + 8625229 = 8625290
  • 103 + 8625187 = 8625290
  • 199 + 8625091 = 8625290
  • 277 + 8625013 = 8625290
  • 283 + 8625007 = 8625290
  • 337 + 8624953 = 8625290
  • 409 + 8624881 = 8625290

Showing the first eight; more decompositions exist.
