Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545198, here are decompositions:
- 7 + 31545191 = 31545198
- 17 + 31545181 = 31545198
- 79 + 31545119 = 31545198
- 101 + 31545097 = 31545198
- 107 + 31545091 = 31545198
- 131 + 31545067 = 31545198
- 137 + 31545061 = 31545198
- 149 + 31545049 = 31545198
Showing the first eight; more decompositions exist.
