Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454468, here are decompositions:

  • 7 + 31454461 = 31454468
  • 37 + 31454431 = 31454468
  • 79 + 31454389 = 31454468
  • 271 + 31454197 = 31454468
  • 277 + 31454191 = 31454468
  • 307 + 31454161 = 31454468
  • 499 + 31453969 = 31454468
  • 571 + 31453897 = 31454468

Showing the first eight; more decompositions exist.
