Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178248, here are decompositions:
- 17 + 178231 = 178248
- 41 + 178207 = 178248
- 61 + 178187 = 178248
- 79 + 178169 = 178248
- 97 + 178151 = 178248
- 107 + 178141 = 178248
- 131 + 178117 = 178248
- 157 + 178091 = 178248
Showing the first eight; more decompositions exist.
