Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 344, here are decompositions:

  • 7 + 337 = 344
  • 13 + 331 = 344
  • 31 + 313 = 344
  • 37 + 307 = 344
  • 61 + 283 = 344
  • 67 + 277 = 344
  • 73 + 271 = 344
  • 103 + 241 = 344

Showing the first eight; more decompositions exist.
