Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548456, here are decompositions:

  • 13 + 31548443 = 31548456
  • 29 + 31548427 = 31548456
  • 113 + 31548343 = 31548456
  • 157 + 31548299 = 31548456
  • 193 + 31548263 = 31548456
  • 307 + 31548149 = 31548456
  • 347 + 31548109 = 31548456
  • 353 + 31548103 = 31548456

Showing the first eight; more decompositions exist.
