Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2404, here are decompositions:
- 5 + 2399 = 2404
- 11 + 2393 = 2404
- 23 + 2381 = 2404
- 47 + 2357 = 2404
- 53 + 2351 = 2404
- 71 + 2333 = 2404
- 107 + 2297 = 2404
- 131 + 2273 = 2404
Showing the first eight; more decompositions exist.
