Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77198, here are decompositions:
- 7 + 77191 = 77198
- 31 + 77167 = 77198
- 61 + 77137 = 77198
- 97 + 77101 = 77198
- 151 + 77047 = 77198
- 157 + 77041 = 77198
- 181 + 77017 = 77198
- 367 + 76831 = 77198
Showing the first eight; more decompositions exist.
