Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533408, here are decompositions:
- 19 + 31533389 = 31533408
- 29 + 31533379 = 31533408
- 37 + 31533371 = 31533408
- 139 + 31533269 = 31533408
- 149 + 31533259 = 31533408
- 199 + 31533209 = 31533408
- 241 + 31533167 = 31533408
- 281 + 31533127 = 31533408
Showing the first eight; more decompositions exist.
