Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12080, here are decompositions:
- 7 + 12073 = 12080
- 31 + 12049 = 12080
- 37 + 12043 = 12080
- 43 + 12037 = 12080
- 73 + 12007 = 12080
- 109 + 11971 = 12080
- 127 + 11953 = 12080
- 139 + 11941 = 12080
Showing the first eight; more decompositions exist.
