Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182378, here are decompositions:
- 37 + 182341 = 182378
- 139 + 182239 = 182378
- 199 + 182179 = 182378
- 211 + 182167 = 182378
- 271 + 182107 = 182378
- 277 + 182101 = 182378
- 331 + 182047 = 182378
- 337 + 182041 = 182378
Showing the first eight; more decompositions exist.
