Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78398, here are decompositions:
- 31 + 78367 = 78398
- 97 + 78301 = 78398
- 139 + 78259 = 78398
- 157 + 78241 = 78398
- 241 + 78157 = 78398
- 277 + 78121 = 78398
- 349 + 78049 = 78398
- 367 + 78031 = 78398
Showing the first eight; more decompositions exist.
