Goldbach decomposition

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.
