Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80408, here are decompositions:
- 61 + 80347 = 80408
- 67 + 80341 = 80408
- 79 + 80329 = 80408
- 157 + 80251 = 80408
- 199 + 80209 = 80408
- 241 + 80167 = 80408
- 331 + 80077 = 80408
- 337 + 80071 = 80408
Showing the first eight; more decompositions exist.
