Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30356, here are decompositions:
- 37 + 30319 = 30356
- 43 + 30313 = 30356
- 97 + 30259 = 30356
- 103 + 30253 = 30356
- 223 + 30133 = 30356
- 367 + 29989 = 30356
- 373 + 29983 = 30356
- 397 + 29959 = 30356
Showing the first eight; more decompositions exist.
