Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738398, here are decompositions:
- 47 + 8738351 = 8738398
- 59 + 8738339 = 8738398
- 167 + 8738231 = 8738398
- 197 + 8738201 = 8738398
- 269 + 8738129 = 8738398
- 311 + 8738087 = 8738398
- 419 + 8737979 = 8738398
- 569 + 8737829 = 8738398
Showing the first eight; more decompositions exist.
