Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 368, here are decompositions:

  • 19 + 349 = 368
  • 31 + 337 = 368
  • 37 + 331 = 368
  • 61 + 307 = 368
  • 97 + 271 = 368
  • 127 + 241 = 368
  • 139 + 229 = 368
  • 157 + 211 = 368

Showing the first eight; more decompositions exist.
