Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42080, here are decompositions:
- 7 + 42073 = 42080
- 19 + 42061 = 42080
- 37 + 42043 = 42080
- 61 + 42019 = 42080
- 67 + 42013 = 42080
- 97 + 41983 = 42080
- 127 + 41953 = 42080
- 139 + 41941 = 42080
Showing the first eight; more decompositions exist.
