Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78740, here are decompositions:
- 3 + 78737 = 78740
- 19 + 78721 = 78740
- 43 + 78697 = 78740
- 97 + 78643 = 78740
- 157 + 78583 = 78740
- 163 + 78577 = 78740
- 199 + 78541 = 78740
- 223 + 78517 = 78740
Showing the first eight; more decompositions exist.
