Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544176, here are decompositions:
- 5 + 31544171 = 31544176
- 23 + 31544153 = 31544176
- 137 + 31544039 = 31544176
- 179 + 31543997 = 31544176
- 197 + 31543979 = 31544176
- 263 + 31543913 = 31544176
- 269 + 31543907 = 31544176
- 317 + 31543859 = 31544176
Showing the first eight; more decompositions exist.
