Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530852, here are decompositions:
- 11 + 31530841 = 31530852
- 19 + 31530833 = 31530852
- 53 + 31530799 = 31530852
- 79 + 31530773 = 31530852
- 139 + 31530713 = 31530852
- 149 + 31530703 = 31530852
- 151 + 31530701 = 31530852
- 173 + 31530679 = 31530852
Showing the first eight; more decompositions exist.
