Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51164, here are decompositions:
- 7 + 51157 = 51164
- 13 + 51151 = 51164
- 31 + 51133 = 51164
- 103 + 51061 = 51164
- 163 + 51001 = 51164
- 193 + 50971 = 51164
- 241 + 50923 = 51164
- 271 + 50893 = 51164
Showing the first eight; more decompositions exist.
