Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80146, here are decompositions:
- 5 + 80141 = 80146
- 107 + 80039 = 80146
- 149 + 79997 = 80146
- 167 + 79979 = 80146
- 173 + 79973 = 80146
- 179 + 79967 = 80146
- 239 + 79907 = 80146
- 257 + 79889 = 80146
Showing the first eight; more decompositions exist.
