Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543108, here are decompositions:
- 5 + 31543103 = 31543108
- 29 + 31543079 = 31543108
- 41 + 31543067 = 31543108
- 89 + 31543019 = 31543108
- 137 + 31542971 = 31543108
- 167 + 31542941 = 31543108
- 197 + 31542911 = 31543108
- 227 + 31542881 = 31543108
Showing the first eight; more decompositions exist.
