Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163378, here are decompositions:
- 11 + 163367 = 163378
- 41 + 163337 = 163378
- 71 + 163307 = 163378
- 167 + 163211 = 163378
- 179 + 163199 = 163378
- 197 + 163181 = 163378
- 227 + 163151 = 163378
- 251 + 163127 = 163378
Showing the first eight; more decompositions exist.
