Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524210, here are decompositions:

  • 13 + 31524197 = 31524210
  • 17 + 31524193 = 31524210
  • 43 + 31524167 = 31524210
  • 103 + 31524107 = 31524210
  • 163 + 31524047 = 31524210
  • 167 + 31524043 = 31524210
  • 197 + 31524013 = 31524210
  • 199 + 31524011 = 31524210

Showing the first eight; more decompositions exist.
