Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533388, here are decompositions:
- 17 + 31533371 = 31533388
- 179 + 31533209 = 31533388
- 197 + 31533191 = 31533388
- 239 + 31533149 = 31533388
- 269 + 31533119 = 31533388
- 389 + 31532999 = 31533388
- 449 + 31532939 = 31533388
- 521 + 31532867 = 31533388
Showing the first eight; more decompositions exist.
