Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30238, here are decompositions:
- 41 + 30197 = 30238
- 101 + 30137 = 30238
- 149 + 30089 = 30238
- 167 + 30071 = 30238
- 179 + 30059 = 30238
- 191 + 30047 = 30238
- 227 + 30011 = 30238
- 311 + 29927 = 30238
Showing the first eight; more decompositions exist.
