Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30388, here are decompositions:
- 41 + 30347 = 30388
- 47 + 30341 = 30388
- 191 + 30197 = 30388
- 227 + 30161 = 30388
- 251 + 30137 = 30388
- 269 + 30119 = 30388
- 317 + 30071 = 30388
- 359 + 30029 = 30388
Showing the first eight; more decompositions exist.
