Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532376, here are decompositions:
- 23 + 31532353 = 31532376
- 37 + 31532339 = 31532376
- 47 + 31532329 = 31532376
- 53 + 31532323 = 31532376
- 97 + 31532279 = 31532376
- 107 + 31532269 = 31532376
- 149 + 31532227 = 31532376
- 157 + 31532219 = 31532376
Showing the first eight; more decompositions exist.
