Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532274, here are decompositions:
- 5 + 31532269 = 31532274
- 13 + 31532261 = 31532274
- 47 + 31532227 = 31532274
- 71 + 31532203 = 31532274
- 107 + 31532167 = 31532274
- 157 + 31532117 = 31532274
- 211 + 31532063 = 31532274
- 271 + 31532003 = 31532274
Showing the first eight; more decompositions exist.
