Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4358, here are decompositions:
- 19 + 4339 = 4358
- 31 + 4327 = 4358
- 61 + 4297 = 4358
- 97 + 4261 = 4358
- 127 + 4231 = 4358
- 139 + 4219 = 4358
- 157 + 4201 = 4358
- 181 + 4177 = 4358
Showing the first eight; more decompositions exist.
