Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40208, here are decompositions:

  • 19 + 40189 = 40208
  • 31 + 40177 = 40208
  • 79 + 40129 = 40208
  • 97 + 40111 = 40208
  • 109 + 40099 = 40208
  • 199 + 40009 = 40208
  • 229 + 39979 = 40208
  • 271 + 39937 = 40208

Showing the first eight; more decompositions exist.
