Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532432, here are decompositions:
- 3 + 31532429 = 31532432
- 31 + 31532401 = 31532432
- 79 + 31532353 = 31532432
- 103 + 31532329 = 31532432
- 109 + 31532323 = 31532432
- 163 + 31532269 = 31532432
- 223 + 31532209 = 31532432
- 229 + 31532203 = 31532432
Showing the first eight; more decompositions exist.
