Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178504, here are decompositions:
- 3 + 178501 = 178504
- 17 + 178487 = 178504
- 23 + 178481 = 178504
- 101 + 178403 = 178504
- 107 + 178397 = 178504
- 197 + 178307 = 178504
- 257 + 178247 = 178504
- 281 + 178223 = 178504
Showing the first eight; more decompositions exist.
