Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544922, here are decompositions:
- 23 + 31544899 = 31544922
- 43 + 31544879 = 31544922
- 103 + 31544819 = 31544922
- 139 + 31544783 = 31544922
- 151 + 31544771 = 31544922
- 163 + 31544759 = 31544922
- 173 + 31544749 = 31544922
- 349 + 31544573 = 31544922
Showing the first eight; more decompositions exist.
