Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525798, here are decompositions:

  • 11 + 31525787 = 31525798
  • 149 + 31525649 = 31525798
  • 191 + 31525607 = 31525798
  • 197 + 31525601 = 31525798
  • 401 + 31525397 = 31525798
  • 419 + 31525379 = 31525798
  • 431 + 31525367 = 31525798
  • 467 + 31525331 = 31525798

Showing the first eight; more decompositions exist.
