Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542030, here are decompositions:
- 7 + 31542023 = 31542030
- 17 + 31542013 = 31542030
- 19 + 31542011 = 31542030
- 29 + 31542001 = 31542030
- 41 + 31541989 = 31542030
- 53 + 31541977 = 31542030
- 59 + 31541971 = 31542030
- 97 + 31541933 = 31542030
Showing the first eight; more decompositions exist.
