Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464918, here are decompositions:
- 97 + 31464821 = 31464918
- 109 + 31464809 = 31464918
- 131 + 31464787 = 31464918
- 137 + 31464781 = 31464918
- 269 + 31464649 = 31464918
- 337 + 31464581 = 31464918
- 347 + 31464571 = 31464918
- 409 + 31464509 = 31464918
Showing the first eight; more decompositions exist.
