Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30256, here are decompositions:
- 3 + 30253 = 30256
- 53 + 30203 = 30256
- 59 + 30197 = 30256
- 137 + 30119 = 30256
- 167 + 30089 = 30256
- 197 + 30059 = 30256
- 227 + 30029 = 30256
- 383 + 29873 = 30256
Showing the first eight; more decompositions exist.
