Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524904, here are decompositions:

  • 11 + 31524893 = 31524904
  • 41 + 31524863 = 31524904
  • 107 + 31524797 = 31524904
  • 113 + 31524791 = 31524904
  • 137 + 31524767 = 31524904
  • 227 + 31524677 = 31524904
  • 263 + 31524641 = 31524904
  • 317 + 31524587 = 31524904

Showing the first eight; more decompositions exist.
