Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7398, here are decompositions:
- 5 + 7393 = 7398
- 29 + 7369 = 7398
- 47 + 7351 = 7398
- 67 + 7331 = 7398
- 89 + 7309 = 7398
- 101 + 7297 = 7398
- 151 + 7247 = 7398
- 179 + 7219 = 7398
Showing the first eight; more decompositions exist.
