Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169144, here are decompositions:
- 47 + 169097 = 169144
- 137 + 169007 = 169144
- 167 + 168977 = 169144
- 251 + 168893 = 169144
- 257 + 168887 = 169144
- 281 + 168863 = 169144
- 293 + 168851 = 169144
- 383 + 168761 = 169144
Showing the first eight; more decompositions exist.
