Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157184, here are decompositions:
- 3 + 157181 = 157184
- 7 + 157177 = 157184
- 43 + 157141 = 157184
- 103 + 157081 = 157184
- 127 + 157057 = 157184
- 241 + 156943 = 157184
- 271 + 156913 = 157184
- 283 + 156901 = 157184
Showing the first eight; more decompositions exist.
