Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527018, here are decompositions:
- 7 + 31527011 = 31527018
- 79 + 31526939 = 31527018
- 97 + 31526921 = 31527018
- 137 + 31526881 = 31527018
- 139 + 31526879 = 31527018
- 199 + 31526819 = 31527018
- 227 + 31526791 = 31527018
- 241 + 31526777 = 31527018
Showing the first eight; more decompositions exist.
