Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91438, here are decompositions:

  • 5 + 91433 = 91438
  • 41 + 91397 = 91438
  • 71 + 91367 = 91438
  • 107 + 91331 = 91438
  • 239 + 91199 = 91438
  • 311 + 91127 = 91438
  • 317 + 91121 = 91438
  • 359 + 91079 = 91438

Showing the first eight; more decompositions exist.
