Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524948, here are decompositions:

  • 11 + 31524937 = 31524948
  • 109 + 31524839 = 31524948
  • 139 + 31524809 = 31524948
  • 151 + 31524797 = 31524948
  • 157 + 31524791 = 31524948
  • 181 + 31524767 = 31524948
  • 227 + 31524721 = 31524948
  • 271 + 31524677 = 31524948

Showing the first eight; more decompositions exist.
