Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525534, here are decompositions:

  • 113 + 31525421 = 31525534
  • 137 + 31525397 = 31525534
  • 167 + 31525367 = 31525534
  • 191 + 31525343 = 31525534
  • 251 + 31525283 = 31525534
  • 431 + 31525103 = 31525534
  • 503 + 31525031 = 31525534
  • 641 + 31524893 = 31525534

Showing the first eight; more decompositions exist.
