Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525032, here are decompositions:

  • 5 + 31525027 = 31525032
  • 41 + 31524991 = 31525032
  • 43 + 31524989 = 31525032
  • 139 + 31524893 = 31525032
  • 193 + 31524839 = 31525032
  • 223 + 31524809 = 31525032
  • 239 + 31524793 = 31525032
  • 241 + 31524791 = 31525032

Showing the first eight; more decompositions exist.
