Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40318, here are decompositions:

  • 29 + 40289 = 40318
  • 41 + 40277 = 40318
  • 149 + 40169 = 40318
  • 167 + 40151 = 40318
  • 191 + 40127 = 40318
  • 281 + 40037 = 40318
  • 347 + 39971 = 40318
  • 389 + 39929 = 40318

Showing the first eight; more decompositions exist.
