Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28374, here are decompositions:
- 23 + 28351 = 28374
- 67 + 28307 = 28374
- 97 + 28277 = 28374
- 163 + 28211 = 28374
- 173 + 28201 = 28374
- 191 + 28183 = 28374
- 193 + 28181 = 28374
- 211 + 28163 = 28374
Showing the first eight; more decompositions exist.
