Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27172, here are decompositions:
- 29 + 27143 = 27172
- 113 + 27059 = 27172
- 179 + 26993 = 27172
- 191 + 26981 = 27172
- 251 + 26921 = 27172
- 269 + 26903 = 27172
- 281 + 26891 = 27172
- 293 + 26879 = 27172
Showing the first eight; more decompositions exist.
