Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525108, here are decompositions:

  • 5 + 31525103 = 31525108
  • 71 + 31525037 = 31525108
  • 101 + 31525007 = 31525108
  • 269 + 31524839 = 31525108
  • 311 + 31524797 = 31525108
  • 317 + 31524791 = 31525108
  • 431 + 31524677 = 31525108
  • 467 + 31524641 = 31525108

Showing the first eight; more decompositions exist.
