Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520024, here are decompositions:
- 7 + 31520017 = 31520024
- 13 + 31520011 = 31520024
- 37 + 31519987 = 31520024
- 73 + 31519951 = 31520024
- 97 + 31519927 = 31520024
- 181 + 31519843 = 31520024
- 223 + 31519801 = 31520024
- 241 + 31519783 = 31520024
Showing the first eight; more decompositions exist.
