Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78208, here are decompositions:
- 5 + 78203 = 78208
- 17 + 78191 = 78208
- 29 + 78179 = 78208
- 41 + 78167 = 78208
- 71 + 78137 = 78208
- 107 + 78101 = 78208
- 149 + 78059 = 78208
- 167 + 78041 = 78208
Showing the first eight; more decompositions exist.
