Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28358, here are decompositions:
- 7 + 28351 = 28358
- 61 + 28297 = 28358
- 79 + 28279 = 28358
- 139 + 28219 = 28358
- 157 + 28201 = 28358
- 271 + 28087 = 28358
- 277 + 28081 = 28358
- 307 + 28051 = 28358
Showing the first eight; more decompositions exist.
