Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22398, here are decompositions:
- 7 + 22391 = 22398
- 17 + 22381 = 22398
- 29 + 22369 = 22398
- 31 + 22367 = 22398
- 107 + 22291 = 22398
- 127 + 22271 = 22398
- 139 + 22259 = 22398
- 151 + 22247 = 22398
Showing the first eight; more decompositions exist.
