Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548142, here are decompositions:

19 + 548123 = 548142
43 + 548099 = 548142
53 + 548089 = 548142
59 + 548083 = 548142
73 + 548069 = 548142
83 + 548059 = 548142
103 + 548039 = 548142
139 + 548003 = 548142

Showing the first eight; more decompositions exist.
