Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526072, here are decompositions:
- 3 + 31526069 = 31526072
- 163 + 31525909 = 31526072
- 181 + 31525891 = 31526072
- 223 + 31525849 = 31526072
- 349 + 31525723 = 31526072
- 373 + 31525699 = 31526072
- 421 + 31525651 = 31526072
- 463 + 31525609 = 31526072
Showing the first eight; more decompositions exist.
