Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564108, here are decompositions:
- 5 + 31564103 = 31564108
- 29 + 31564079 = 31564108
- 167 + 31563941 = 31564108
- 179 + 31563929 = 31564108
- 197 + 31563911 = 31564108
- 227 + 31563881 = 31564108
- 281 + 31563827 = 31564108
- 461 + 31563647 = 31564108
Showing the first eight; more decompositions exist.
