Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524900, here are decompositions:

  • 7 + 31524893 = 31524900
  • 37 + 31524863 = 31524900
  • 61 + 31524839 = 31524900
  • 103 + 31524797 = 31524900
  • 107 + 31524793 = 31524900
  • 109 + 31524791 = 31524900
  • 137 + 31524763 = 31524900
  • 179 + 31524721 = 31524900

Showing the first eight; more decompositions exist.
