Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531110, here are decompositions:
- 11 + 31531099 = 31531110
- 31 + 31531079 = 31531110
- 41 + 31531069 = 31531110
- 47 + 31531063 = 31531110
- 53 + 31531057 = 31531110
- 109 + 31531001 = 31531110
- 131 + 31530979 = 31531110
- 137 + 31530973 = 31531110
Showing the first eight; more decompositions exist.
