Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47400, here are decompositions:

  • 11 + 47389 = 47400
  • 13 + 47387 = 47400
  • 19 + 47381 = 47400
  • 37 + 47363 = 47400
  • 47 + 47353 = 47400
  • 61 + 47339 = 47400
  • 83 + 47317 = 47400
  • 97 + 47303 = 47400

Showing the first eight; more decompositions exist.
