Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534112, here are decompositions:
- 61 + 31534051 = 31534112
- 79 + 31534033 = 31534112
- 163 + 31533949 = 31534112
- 193 + 31533919 = 31534112
- 241 + 31533871 = 31534112
- 283 + 31533829 = 31534112
- 349 + 31533763 = 31534112
- 499 + 31533613 = 31534112
Showing the first eight; more decompositions exist.
