Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584310, here are decompositions:

  • 3 + 31584307 = 31584310
  • 11 + 31584299 = 31584310
  • 29 + 31584281 = 31584310
  • 47 + 31584263 = 31584310
  • 113 + 31584197 = 31584310
  • 137 + 31584173 = 31584310
  • 167 + 31584143 = 31584310
  • 311 + 31583999 = 31584310

Showing the first eight; more decompositions exist.
