Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526920, here are decompositions:
- 17 + 31526903 = 31526920
- 41 + 31526879 = 31526920
- 101 + 31526819 = 31526920
- 149 + 31526771 = 31526920
- 167 + 31526753 = 31526920
- 197 + 31526723 = 31526920
- 251 + 31526669 = 31526920
- 317 + 31526603 = 31526920
Showing the first eight; more decompositions exist.
