Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532384, here are decompositions:

  • 31 + 31532353 = 31532384
  • 43 + 31532341 = 31532384
  • 61 + 31532323 = 31532384
  • 157 + 31532227 = 31532384
  • 181 + 31532203 = 31532384
  • 271 + 31532113 = 31532384
  • 313 + 31532071 = 31532384
  • 463 + 31531921 = 31532384

Showing the first eight; more decompositions exist.
