Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532358, here are decompositions:
- 5 + 31532353 = 31532358
- 17 + 31532341 = 31532358
- 19 + 31532339 = 31532358
- 29 + 31532329 = 31532358
- 79 + 31532279 = 31532358
- 89 + 31532269 = 31532358
- 97 + 31532261 = 31532358
- 131 + 31532227 = 31532358
Showing the first eight; more decompositions exist.
