Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80540, here are decompositions:
- 3 + 80537 = 80540
- 13 + 80527 = 80540
- 67 + 80473 = 80540
- 193 + 80347 = 80540
- 199 + 80341 = 80540
- 211 + 80329 = 80540
- 223 + 80317 = 80540
- 277 + 80263 = 80540
Showing the first eight; more decompositions exist.
