Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542024, here are decompositions:
- 11 + 31542013 = 31542024
- 13 + 31542011 = 31542024
- 23 + 31542001 = 31542024
- 43 + 31541981 = 31542024
- 47 + 31541977 = 31542024
- 53 + 31541971 = 31542024
- 131 + 31541893 = 31542024
- 167 + 31541857 = 31542024
Showing the first eight; more decompositions exist.
