Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525458, here are decompositions:

  • 11 + 31525447 = 31525458
  • 37 + 31525421 = 31525458
  • 61 + 31525397 = 31525458
  • 79 + 31525379 = 31525458
  • 127 + 31525331 = 31525458
  • 179 + 31525279 = 31525458
  • 191 + 31525267 = 31525458
  • 197 + 31525261 = 31525458

Showing the first eight; more decompositions exist.
