Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29188, here are decompositions:
- 41 + 29147 = 29188
- 59 + 29129 = 29188
- 167 + 29021 = 29188
- 179 + 29009 = 29188
- 227 + 28961 = 29188
- 239 + 28949 = 29188
- 317 + 28871 = 29188
- 491 + 28697 = 29188
Showing the first eight; more decompositions exist.
