Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606440, here are decompositions:

  • 53 + 8606387 = 8606440
  • 113 + 8606327 = 8606440
  • 131 + 8606309 = 8606440
  • 179 + 8606261 = 8606440
  • 239 + 8606201 = 8606440
  • 347 + 8606093 = 8606440
  • 389 + 8606051 = 8606440
  • 443 + 8605997 = 8606440

Showing the first eight; more decompositions exist.
