Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525006, here are decompositions:

  • 17 + 31524989 = 31525006
  • 113 + 31524893 = 31525006
  • 167 + 31524839 = 31525006
  • 197 + 31524809 = 31525006
  • 239 + 31524767 = 31525006
  • 419 + 31524587 = 31525006
  • 587 + 31524419 = 31525006
  • 809 + 31524197 = 31525006

Showing the first eight; more decompositions exist.
