Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524944, here are decompositions:

  • 7 + 31524937 = 31524944
  • 151 + 31524793 = 31524944
  • 181 + 31524763 = 31524944
  • 223 + 31524721 = 31524944
  • 271 + 31524673 = 31524944
  • 337 + 31524607 = 31524944
  • 421 + 31524523 = 31524944
  • 541 + 31524403 = 31524944

Showing the first eight; more decompositions exist.
