Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548128, here are decompositions:

5 + 548123 = 548128
11 + 548117 = 548128
29 + 548099 = 548128
59 + 548069 = 548128
89 + 548039 = 548128
227 + 547901 = 548128
239 + 547889 = 548128
257 + 547871 = 548128

Showing the first eight; more decompositions exist.
