Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178444, here are decompositions:
- 3 + 178441 = 178444
- 5 + 178439 = 178444
- 41 + 178403 = 178444
- 47 + 178397 = 178444
- 83 + 178361 = 178444
- 137 + 178307 = 178444
- 197 + 178247 = 178444
- 257 + 178187 = 178444
Showing the first eight; more decompositions exist.
