Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533448, here are decompositions:
- 17 + 31533431 = 31533448
- 59 + 31533389 = 31533448
- 179 + 31533269 = 31533448
- 239 + 31533209 = 31533448
- 257 + 31533191 = 31533448
- 281 + 31533167 = 31533448
- 347 + 31533101 = 31533448
- 449 + 31532999 = 31533448
Showing the first eight; more decompositions exist.
