Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478398, here are decompositions:
- 7 + 478391 = 478398
- 47 + 478351 = 478398
- 59 + 478339 = 478398
- 127 + 478271 = 478398
- 139 + 478259 = 478398
- 157 + 478241 = 478398
- 191 + 478207 = 478398
- 199 + 478199 = 478398
Showing the first eight; more decompositions exist.
