Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5378, here are decompositions:
- 31 + 5347 = 5378
- 97 + 5281 = 5378
- 151 + 5227 = 5378
- 181 + 5197 = 5378
- 199 + 5179 = 5378
- 211 + 5167 = 5378
- 271 + 5107 = 5378
- 277 + 5101 = 5378
Showing the first eight; more decompositions exist.
