Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6398, here are decompositions:
- 19 + 6379 = 6398
- 31 + 6367 = 6398
- 37 + 6361 = 6398
- 61 + 6337 = 6398
- 97 + 6301 = 6398
- 127 + 6271 = 6398
- 151 + 6247 = 6398
- 181 + 6217 = 6398
Showing the first eight; more decompositions exist.
