Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458024, here are decompositions:
- 11 + 31458013 = 31458024
- 113 + 31457911 = 31458024
- 163 + 31457861 = 31458024
- 167 + 31457857 = 31458024
- 181 + 31457843 = 31458024
- 193 + 31457831 = 31458024
- 271 + 31457753 = 31458024
- 281 + 31457743 = 31458024
Showing the first eight; more decompositions exist.
