Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6398, here are decompositions:

  • 19 + 6379 = 6398
  • 31 + 6367 = 6398
  • 37 + 6361 = 6398
  • 61 + 6337 = 6398
  • 97 + 6301 = 6398
  • 127 + 6271 = 6398
  • 151 + 6247 = 6398
  • 181 + 6217 = 6398

Showing the first eight; more decompositions exist.
