Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526828, here are decompositions:
- 19 + 31526809 = 31526828
- 37 + 31526791 = 31526828
- 79 + 31526749 = 31526828
- 97 + 31526731 = 31526828
- 139 + 31526689 = 31526828
- 181 + 31526647 = 31526828
- 211 + 31526617 = 31526828
- 331 + 31526497 = 31526828
Showing the first eight; more decompositions exist.
