Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458000, here are decompositions:
- 11 + 31457989 = 31458000
- 31 + 31457969 = 31458000
- 71 + 31457929 = 31458000
- 89 + 31457911 = 31458000
- 97 + 31457903 = 31458000
- 131 + 31457869 = 31458000
- 139 + 31457861 = 31458000
- 151 + 31457849 = 31458000
Showing the first eight; more decompositions exist.
