Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545740, here are decompositions:
- 3 + 31545737 = 31545740
- 73 + 31545667 = 31545740
- 241 + 31545499 = 31545740
- 271 + 31545469 = 31545740
- 349 + 31545391 = 31545740
- 367 + 31545373 = 31545740
- 397 + 31545343 = 31545740
- 409 + 31545331 = 31545740
Showing the first eight; more decompositions exist.
