Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541928, here are decompositions:
- 29 + 31541899 = 31541928
- 37 + 31541891 = 31541928
- 59 + 31541869 = 31541928
- 71 + 31541857 = 31541928
- 101 + 31541827 = 31541928
- 167 + 31541761 = 31541928
- 191 + 31541737 = 31541928
- 251 + 31541677 = 31541928
Showing the first eight; more decompositions exist.
