Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31080, here are decompositions:
- 11 + 31069 = 31080
- 17 + 31063 = 31080
- 29 + 31051 = 31080
- 41 + 31039 = 31080
- 47 + 31033 = 31080
- 61 + 31019 = 31080
- 67 + 31013 = 31080
- 97 + 30983 = 31080
Showing the first eight; more decompositions exist.
