Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524864, here are decompositions:

  • 67 + 31524797 = 31524864
  • 71 + 31524793 = 31524864
  • 73 + 31524791 = 31524864
  • 97 + 31524767 = 31524864
  • 101 + 31524763 = 31524864
  • 191 + 31524673 = 31524864
  • 223 + 31524641 = 31524864
  • 257 + 31524607 = 31524864

Showing the first eight; more decompositions exist.
