Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526878, here are decompositions:
- 59 + 31526819 = 31526878
- 101 + 31526777 = 31526878
- 107 + 31526771 = 31526878
- 389 + 31526489 = 31526878
- 401 + 31526477 = 31526878
- 491 + 31526387 = 31526878
- 809 + 31526069 = 31526878
- 821 + 31526057 = 31526878
Showing the first eight; more decompositions exist.
