Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531176, here are decompositions:
- 13 + 31531163 = 31531176
- 37 + 31531139 = 31531176
- 59 + 31531117 = 31531176
- 97 + 31531079 = 31531176
- 107 + 31531069 = 31531176
- 113 + 31531063 = 31531176
- 197 + 31530979 = 31531176
- 199 + 31530977 = 31531176
Showing the first eight; more decompositions exist.
