Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532216, here are decompositions:
- 7 + 31532209 = 31532216
- 13 + 31532203 = 31532216
- 103 + 31532113 = 31532216
- 127 + 31532089 = 31532216
- 307 + 31531909 = 31532216
- 577 + 31531639 = 31532216
- 733 + 31531483 = 31532216
- 967 + 31531249 = 31532216
Showing the first eight; more decompositions exist.
