Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 300, here are decompositions:

  • 7 + 293 = 300
  • 17 + 283 = 300
  • 19 + 281 = 300
  • 23 + 277 = 300
  • 29 + 271 = 300
  • 31 + 269 = 300
  • 37 + 263 = 300
  • 43 + 257 = 300

Showing the first eight; more decompositions exist.
