Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708388, here are decompositions:

  • 97 + 8708291 = 8708388
  • 127 + 8708261 = 8708388
  • 191 + 8708197 = 8708388
  • 229 + 8708159 = 8708388
  • 307 + 8708081 = 8708388
  • 317 + 8708071 = 8708388
  • 349 + 8708039 = 8708388
  • 389 + 8707999 = 8708388

Showing the first eight; more decompositions exist.
