Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525768, here are decompositions:

  • 5 + 31525763 = 31525768
  • 167 + 31525601 = 31525768
  • 179 + 31525589 = 31525768
  • 269 + 31525499 = 31525768
  • 347 + 31525421 = 31525768
  • 389 + 31525379 = 31525768
  • 401 + 31525367 = 31525768
  • 479 + 31525289 = 31525768

Showing the first eight; more decompositions exist.
