Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532332, here are decompositions:
- 3 + 31532329 = 31532332
- 53 + 31532279 = 31532332
- 71 + 31532261 = 31532332
- 113 + 31532219 = 31532332
- 191 + 31532141 = 31532332
- 269 + 31532063 = 31532332
- 311 + 31532021 = 31532332
- 401 + 31531931 = 31532332
Showing the first eight; more decompositions exist.
