Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524918, here are decompositions:

  • 79 + 31524839 = 31524918
  • 109 + 31524809 = 31524918
  • 127 + 31524791 = 31524918
  • 151 + 31524767 = 31524918
  • 197 + 31524721 = 31524918
  • 241 + 31524677 = 31524918
  • 277 + 31524641 = 31524918
  • 311 + 31524607 = 31524918

Showing the first eight; more decompositions exist.
