Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548440, here are decompositions:
- 13 + 31548427 = 31548440
- 97 + 31548343 = 31548440
- 109 + 31548331 = 31548440
- 127 + 31548313 = 31548440
- 139 + 31548301 = 31548440
- 307 + 31548133 = 31548440
- 331 + 31548109 = 31548440
- 337 + 31548103 = 31548440
Showing the first eight; more decompositions exist.
