Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78212, here are decompositions:
- 19 + 78193 = 78212
- 73 + 78139 = 78212
- 163 + 78049 = 78212
- 181 + 78031 = 78212
- 229 + 77983 = 78212
- 283 + 77929 = 78212
- 313 + 77899 = 78212
- 349 + 77863 = 78212
Showing the first eight; more decompositions exist.
