Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497904, here are decompositions:
- 41 + 31497863 = 31497904
- 101 + 31497803 = 31497904
- 107 + 31497797 = 31497904
- 131 + 31497773 = 31497904
- 167 + 31497737 = 31497904
- 197 + 31497707 = 31497904
- 233 + 31497671 = 31497904
- 353 + 31497551 = 31497904
Showing the first eight; more decompositions exist.
