Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11644, here are decompositions:
- 11 + 11633 = 11644
- 23 + 11621 = 11644
- 47 + 11597 = 11644
- 173 + 11471 = 11644
- 197 + 11447 = 11644
- 233 + 11411 = 11644
- 251 + 11393 = 11644
- 293 + 11351 = 11644
Showing the first eight; more decompositions exist.
