Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177378, here are decompositions:
- 31 + 177347 = 177378
- 41 + 177337 = 177378
- 59 + 177319 = 177378
- 109 + 177269 = 177378
- 139 + 177239 = 177378
- 167 + 177211 = 177378
- 211 + 177167 = 177378
- 251 + 177127 = 177378
Showing the first eight; more decompositions exist.
