Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526156, here are decompositions:
- 73 + 31526083 = 31526156
- 199 + 31525957 = 31526156
- 229 + 31525927 = 31526156
- 307 + 31525849 = 31526156
- 373 + 31525783 = 31526156
- 379 + 31525777 = 31526156
- 433 + 31525723 = 31526156
- 439 + 31525717 = 31526156
Showing the first eight; more decompositions exist.
