Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27644, here are decompositions:
- 13 + 27631 = 27644
- 61 + 27583 = 27644
- 103 + 27541 = 27644
- 157 + 27487 = 27644
- 163 + 27481 = 27644
- 277 + 27367 = 27644
- 283 + 27361 = 27644
- 307 + 27337 = 27644
Showing the first eight; more decompositions exist.
