Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72198, here are decompositions:
- 29 + 72169 = 72198
- 31 + 72167 = 72198
- 37 + 72161 = 72198
- 59 + 72139 = 72198
- 89 + 72109 = 72198
- 97 + 72101 = 72198
- 107 + 72091 = 72198
- 109 + 72089 = 72198
Showing the first eight; more decompositions exist.
