Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8408, here are decompositions:

  • 19 + 8389 = 8408
  • 31 + 8377 = 8408
  • 79 + 8329 = 8408
  • 97 + 8311 = 8408
  • 139 + 8269 = 8408
  • 199 + 8209 = 8408
  • 229 + 8179 = 8408
  • 241 + 8167 = 8408

Showing the first eight; more decompositions exist.
