Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9388, here are decompositions:
- 11 + 9377 = 9388
- 17 + 9371 = 9388
- 47 + 9341 = 9388
- 107 + 9281 = 9388
- 131 + 9257 = 9388
- 149 + 9239 = 9388
- 167 + 9221 = 9388
- 179 + 9209 = 9388
Showing the first eight; more decompositions exist.
