Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40356, here are decompositions:

  • 5 + 40351 = 40356
  • 13 + 40343 = 40356
  • 67 + 40289 = 40356
  • 73 + 40283 = 40356
  • 79 + 40277 = 40356
  • 103 + 40253 = 40356
  • 163 + 40193 = 40356
  • 167 + 40189 = 40356

Showing the first eight; more decompositions exist.
