Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80080, here are decompositions:
- 3 + 80077 = 80080
- 29 + 80051 = 80080
- 41 + 80039 = 80080
- 59 + 80021 = 80080
- 83 + 79997 = 80080
- 101 + 79979 = 80080
- 107 + 79973 = 80080
- 113 + 79967 = 80080
Showing the first eight; more decompositions exist.
