Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531326, here are decompositions:
- 23 + 31531303 = 31531326
- 53 + 31531273 = 31531326
- 59 + 31531267 = 31531326
- 109 + 31531217 = 31531326
- 163 + 31531163 = 31531326
- 227 + 31531099 = 31531326
- 257 + 31531069 = 31531326
- 263 + 31531063 = 31531326
Showing the first eight; more decompositions exist.
