Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482000, here are decompositions:
- 19 + 31481981 = 31482000
- 61 + 31481939 = 31482000
- 79 + 31481921 = 31482000
- 89 + 31481911 = 31482000
- 101 + 31481899 = 31482000
- 113 + 31481887 = 31482000
- 149 + 31481851 = 31482000
- 157 + 31481843 = 31482000
Showing the first eight; more decompositions exist.
