Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533350, here are decompositions:
- 7 + 31533343 = 31533350
- 223 + 31533127 = 31533350
- 337 + 31533013 = 31533350
- 349 + 31533001 = 31533350
- 379 + 31532971 = 31533350
- 487 + 31532863 = 31533350
- 601 + 31532749 = 31533350
- 613 + 31532737 = 31533350
Showing the first eight; more decompositions exist.
