Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548172, here are decompositions:

19 + 548153 = 548172
29 + 548143 = 548172
73 + 548099 = 548172
83 + 548089 = 548172
89 + 548083 = 548172
103 + 548069 = 548172
113 + 548059 = 548172
173 + 547999 = 548172

Showing the first eight; more decompositions exist.
