Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16378, here are decompositions:
- 17 + 16361 = 16378
- 29 + 16349 = 16378
- 59 + 16319 = 16378
- 149 + 16229 = 16378
- 191 + 16187 = 16378
- 239 + 16139 = 16378
- 251 + 16127 = 16378
- 281 + 16097 = 16378
Showing the first eight; more decompositions exist.
