Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532800, here are decompositions:
- 23 + 31532777 = 31532800
- 107 + 31532693 = 31532800
- 113 + 31532687 = 31532800
- 227 + 31532573 = 31532800
- 293 + 31532507 = 31532800
- 311 + 31532489 = 31532800
- 461 + 31532339 = 31532800
- 521 + 31532279 = 31532800
Showing the first eight; more decompositions exist.
