Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526372, here are decompositions:
- 13 + 31526359 = 31526372
- 151 + 31526221 = 31526372
- 181 + 31526191 = 31526372
- 421 + 31525951 = 31526372
- 463 + 31525909 = 31526372
- 523 + 31525849 = 31526372
- 601 + 31525771 = 31526372
- 673 + 31525699 = 31526372
Showing the first eight; more decompositions exist.
