Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691338, here are decompositions:

  • 109 + 8691229 = 8691338
  • 127 + 8691211 = 8691338
  • 151 + 8691187 = 8691338
  • 181 + 8691157 = 8691338
  • 211 + 8691127 = 8691338
  • 367 + 8690971 = 8691338
  • 379 + 8690959 = 8691338
  • 421 + 8690917 = 8691338

Showing the first eight; more decompositions exist.
