Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683420, here are decompositions:

  • 89 + 8683331 = 8683420
  • 101 + 8683319 = 8683420
  • 113 + 8683307 = 8683420
  • 167 + 8683253 = 8683420
  • 197 + 8683223 = 8683420
  • 233 + 8683187 = 8683420
  • 257 + 8683163 = 8683420
  • 359 + 8683061 = 8683420

Showing the first eight; more decompositions exist.
