Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157244, here are decompositions:
- 13 + 157231 = 157244
- 37 + 157207 = 157244
- 67 + 157177 = 157244
- 103 + 157141 = 157244
- 163 + 157081 = 157244
- 193 + 157051 = 157244
- 277 + 156967 = 157244
- 331 + 156913 = 157244
Showing the first eight; more decompositions exist.
