Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542376, here are decompositions:
- 3 + 31542373 = 31542376
- 17 + 31542359 = 31542376
- 53 + 31542323 = 31542376
- 179 + 31542197 = 31542376
- 227 + 31542149 = 31542376
- 263 + 31542113 = 31542376
- 293 + 31542083 = 31542376
- 353 + 31542023 = 31542376
Showing the first eight; more decompositions exist.
