Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545832, here are decompositions:
- 83 + 31545749 = 31545832
- 89 + 31545743 = 31545832
- 191 + 31545641 = 31545832
- 233 + 31545599 = 31545832
- 431 + 31545401 = 31545832
- 503 + 31545329 = 31545832
- 509 + 31545323 = 31545832
- 599 + 31545233 = 31545832
Showing the first eight; more decompositions exist.
