Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6378, here are decompositions:
- 5 + 6373 = 6378
- 11 + 6367 = 6378
- 17 + 6361 = 6378
- 19 + 6359 = 6378
- 41 + 6337 = 6378
- 61 + 6317 = 6378
- 67 + 6311 = 6378
- 79 + 6299 = 6378
Showing the first eight; more decompositions exist.
