Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27404, here are decompositions:
- 7 + 27397 = 27404
- 37 + 27367 = 27404
- 43 + 27361 = 27404
- 67 + 27337 = 27404
- 127 + 27277 = 27404
- 151 + 27253 = 27404
- 163 + 27241 = 27404
- 193 + 27211 = 27404
Showing the first eight; more decompositions exist.
