Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548240, here are decompositions:
- 107 + 31548133 = 31548240
- 131 + 31548109 = 31548240
- 137 + 31548103 = 31548240
- 193 + 31548047 = 31548240
- 211 + 31548029 = 31548240
- 223 + 31548017 = 31548240
- 233 + 31548007 = 31548240
- 281 + 31547959 = 31548240
Showing the first eight; more decompositions exist.
