Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178480, here are decompositions:
- 11 + 178469 = 178480
- 41 + 178439 = 178480
- 83 + 178397 = 178480
- 131 + 178349 = 178480
- 173 + 178307 = 178480
- 179 + 178301 = 178480
- 191 + 178289 = 178480
- 233 + 178247 = 178480
Showing the first eight; more decompositions exist.
