Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533952, here are decompositions:
- 3 + 31533949 = 31533952
- 29 + 31533923 = 31533952
- 41 + 31533911 = 31533952
- 113 + 31533839 = 31533952
- 179 + 31533773 = 31533952
- 293 + 31533659 = 31533952
- 311 + 31533641 = 31533952
- 353 + 31533599 = 31533952
Showing the first eight; more decompositions exist.
