Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72168, here are decompositions:
- 7 + 72161 = 72168
- 29 + 72139 = 72168
- 59 + 72109 = 72168
- 67 + 72101 = 72168
- 79 + 72089 = 72168
- 137 + 72031 = 72168
- 149 + 72019 = 72168
- 181 + 71987 = 72168
Showing the first eight; more decompositions exist.
