Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40290, here are decompositions:

  • 7 + 40283 = 40290
  • 13 + 40277 = 40290
  • 37 + 40253 = 40290
  • 53 + 40237 = 40290
  • 59 + 40231 = 40290
  • 97 + 40193 = 40290
  • 101 + 40189 = 40290
  • 113 + 40177 = 40290

Showing the first eight; more decompositions exist.
