Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525132, here are decompositions:

  • 5 + 31525127 = 31525132
  • 11 + 31525121 = 31525132
  • 29 + 31525103 = 31525132
  • 101 + 31525031 = 31525132
  • 239 + 31524893 = 31525132
  • 269 + 31524863 = 31525132
  • 293 + 31524839 = 31525132
  • 491 + 31524641 = 31525132

Showing the first eight; more decompositions exist.
