Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6388, here are decompositions:
- 29 + 6359 = 6388
- 59 + 6329 = 6388
- 71 + 6317 = 6388
- 89 + 6299 = 6388
- 101 + 6287 = 6388
- 131 + 6257 = 6388
- 167 + 6221 = 6388
- 191 + 6197 = 6388
Showing the first eight; more decompositions exist.
