Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178424, here are decompositions:
- 7 + 178417 = 178424
- 31 + 178393 = 178424
- 73 + 178351 = 178424
- 97 + 178327 = 178424
- 163 + 178261 = 178424
- 193 + 178231 = 178424
- 241 + 178183 = 178424
- 283 + 178141 = 178424
Showing the first eight; more decompositions exist.
