Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532536, here are decompositions:
- 29 + 31532507 = 31532536
- 47 + 31532489 = 31532536
- 59 + 31532477 = 31532536
- 107 + 31532429 = 31532536
- 197 + 31532339 = 31532536
- 257 + 31532279 = 31532536
- 317 + 31532219 = 31532536
- 419 + 31532117 = 31532536
Showing the first eight; more decompositions exist.
