Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79138, here are decompositions:
- 5 + 79133 = 79138
- 107 + 79031 = 79138
- 149 + 78989 = 79138
- 197 + 78941 = 79138
- 251 + 78887 = 79138
- 281 + 78857 = 79138
- 347 + 78791 = 79138
- 359 + 78779 = 79138
Showing the first eight; more decompositions exist.
