Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526030, here are decompositions:
- 73 + 31525957 = 31526030
- 79 + 31525951 = 31526030
- 103 + 31525927 = 31526030
- 127 + 31525903 = 31526030
- 139 + 31525891 = 31526030
- 181 + 31525849 = 31526030
- 307 + 31525723 = 31526030
- 313 + 31525717 = 31526030
Showing the first eight; more decompositions exist.
