Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548018, here are decompositions:
- 11 + 31548007 = 31548018
- 37 + 31547981 = 31548018
- 59 + 31547959 = 31548018
- 97 + 31547921 = 31548018
- 101 + 31547917 = 31548018
- 157 + 31547861 = 31548018
- 167 + 31547851 = 31548018
- 179 + 31547839 = 31548018
Showing the first eight; more decompositions exist.
