Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531296, here are decompositions:
- 23 + 31531273 = 31531296
- 29 + 31531267 = 31531296
- 47 + 31531249 = 31531296
- 79 + 31531217 = 31531296
- 157 + 31531139 = 31531296
- 179 + 31531117 = 31531296
- 197 + 31531099 = 31531296
- 227 + 31531069 = 31531296
Showing the first eight; more decompositions exist.
