Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80880, here are decompositions:
- 17 + 80863 = 80880
- 31 + 80849 = 80880
- 47 + 80833 = 80880
- 61 + 80819 = 80880
- 71 + 80809 = 80880
- 97 + 80783 = 80880
- 101 + 80779 = 80880
- 103 + 80777 = 80880
Showing the first eight; more decompositions exist.
