Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544164, here are decompositions:
- 11 + 31544153 = 31544164
- 107 + 31544057 = 31544164
- 131 + 31544033 = 31544164
- 167 + 31543997 = 31544164
- 173 + 31543991 = 31544164
- 251 + 31543913 = 31544164
- 257 + 31543907 = 31544164
- 293 + 31543871 = 31544164
Showing the first eight; more decompositions exist.
