Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 302, here are decompositions:

  • 19 + 283 = 302
  • 31 + 271 = 302
  • 61 + 241 = 302
  • 73 + 229 = 302
  • 79 + 223 = 302
  • 103 + 199 = 302
  • 109 + 193 = 302
  • 139 + 163 = 302

Showing the first eight; more decompositions exist.
