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.
