Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8404, here are decompositions:
- 17 + 8387 = 8404
- 41 + 8363 = 8404
- 107 + 8297 = 8404
- 113 + 8291 = 8404
- 131 + 8273 = 8404
- 167 + 8237 = 8404
- 173 + 8231 = 8404
- 233 + 8171 = 8404
Showing the first eight; more decompositions exist.
