Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80404, here are decompositions:
- 17 + 80387 = 80404
- 41 + 80363 = 80404
- 131 + 80273 = 80404
- 173 + 80231 = 80404
- 197 + 80207 = 80404
- 227 + 80177 = 80404
- 251 + 80153 = 80404
- 257 + 80147 = 80404
Showing the first eight; more decompositions exist.
