Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29128, here are decompositions:
- 5 + 29123 = 29128
- 101 + 29027 = 29128
- 107 + 29021 = 29128
- 149 + 28979 = 29128
- 167 + 28961 = 29128
- 179 + 28949 = 29128
- 227 + 28901 = 29128
- 257 + 28871 = 29128
Showing the first eight; more decompositions exist.
