Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157124, here are decompositions:
- 43 + 157081 = 157124
- 67 + 157057 = 157124
- 73 + 157051 = 157124
- 157 + 156967 = 157124
- 181 + 156943 = 157124
- 211 + 156913 = 157124
- 223 + 156901 = 157124
- 283 + 156841 = 157124
Showing the first eight; more decompositions exist.
