Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80420, here are decompositions:
- 13 + 80407 = 80420
- 73 + 80347 = 80420
- 79 + 80341 = 80420
- 103 + 80317 = 80420
- 157 + 80263 = 80420
- 181 + 80239 = 80420
- 199 + 80221 = 80420
- 211 + 80209 = 80420
Showing the first eight; more decompositions exist.
