Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532472, here are decompositions:
- 43 + 31532429 = 31532472
- 71 + 31532401 = 31532472
- 131 + 31532341 = 31532472
- 149 + 31532323 = 31532472
- 193 + 31532279 = 31532472
- 211 + 31532261 = 31532472
- 263 + 31532209 = 31532472
- 269 + 31532203 = 31532472
Showing the first eight; more decompositions exist.
