Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16544, here are decompositions:
- 67 + 16477 = 16544
- 97 + 16447 = 16544
- 127 + 16417 = 16544
- 163 + 16381 = 16544
- 181 + 16363 = 16544
- 211 + 16333 = 16544
- 271 + 16273 = 16544
- 277 + 16267 = 16544
Showing the first eight; more decompositions exist.
