Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526918, here are decompositions:
- 19 + 31526899 = 31526918
- 37 + 31526881 = 31526918
- 109 + 31526809 = 31526918
- 127 + 31526791 = 31526918
- 229 + 31526689 = 31526918
- 271 + 31526647 = 31526918
- 421 + 31526497 = 31526918
- 487 + 31526431 = 31526918
Showing the first eight; more decompositions exist.
