Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532160, here are decompositions:
- 19 + 31532141 = 31532160
- 43 + 31532117 = 31532160
- 47 + 31532113 = 31532160
- 71 + 31532089 = 31532160
- 89 + 31532071 = 31532160
- 97 + 31532063 = 31532160
- 139 + 31532021 = 31532160
- 157 + 31532003 = 31532160
Showing the first eight; more decompositions exist.
