Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4398, here are decompositions:
- 7 + 4391 = 4398
- 41 + 4357 = 4398
- 59 + 4339 = 4398
- 61 + 4337 = 4398
- 71 + 4327 = 4398
- 101 + 4297 = 4398
- 109 + 4289 = 4398
- 127 + 4271 = 4398
Showing the first eight; more decompositions exist.
