Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548238, here are decompositions:

11 + 548227 = 548238
17 + 548221 = 548238
37 + 548201 = 548238
139 + 548099 = 548238
149 + 548089 = 548238
179 + 548059 = 548238
199 + 548039 = 548238
239 + 547999 = 548238

Showing the first eight; more decompositions exist.
