Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745540, here are decompositions:

  • 17 + 8745523 = 8745540
  • 47 + 8745493 = 8745540
  • 103 + 8745437 = 8745540
  • 173 + 8745367 = 8745540
  • 197 + 8745343 = 8745540
  • 211 + 8745329 = 8745540
  • 229 + 8745311 = 8745540
  • 233 + 8745307 = 8745540

Showing the first eight; more decompositions exist.
