Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531252, here are decompositions:
- 3 + 31531249 = 31531252
- 89 + 31531163 = 31531252
- 113 + 31531139 = 31531252
- 173 + 31531079 = 31531252
- 251 + 31531001 = 31531252
- 293 + 31530959 = 31531252
- 359 + 31530893 = 31531252
- 419 + 31530833 = 31531252
Showing the first eight; more decompositions exist.
