Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548218, here are decompositions:

5 + 548213 = 548218
17 + 548201 = 548218
29 + 548189 = 548218
101 + 548117 = 548218
149 + 548069 = 548218
179 + 548039 = 548218
317 + 547901 = 548218
347 + 547871 = 548218

Showing the first eight; more decompositions exist.
