Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 354, here are decompositions:

  • 5 + 349 = 354
  • 7 + 347 = 354
  • 17 + 337 = 354
  • 23 + 331 = 354
  • 37 + 317 = 354
  • 41 + 313 = 354
  • 43 + 311 = 354
  • 47 + 307 = 354

Showing the first eight; more decompositions exist.
