Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178462, here are decompositions:
- 23 + 178439 = 178462
- 59 + 178403 = 178462
- 101 + 178361 = 178462
- 113 + 178349 = 178462
- 173 + 178289 = 178462
- 239 + 178223 = 178462
- 293 + 178169 = 178462
- 311 + 178151 = 178462
Showing the first eight; more decompositions exist.
