Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40288, here are decompositions:

  • 5 + 40283 = 40288
  • 11 + 40277 = 40288
  • 47 + 40241 = 40288
  • 137 + 40151 = 40288
  • 251 + 40037 = 40288
  • 257 + 40031 = 40288
  • 317 + 39971 = 40288
  • 359 + 39929 = 40288

Showing the first eight; more decompositions exist.
