Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80280, here are decompositions:
- 7 + 80273 = 80280
- 17 + 80263 = 80280
- 29 + 80251 = 80280
- 41 + 80239 = 80280
- 47 + 80233 = 80280
- 59 + 80221 = 80280
- 71 + 80209 = 80280
- 73 + 80207 = 80280
Showing the first eight; more decompositions exist.
