Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548220, here are decompositions:

7 + 548213 = 548220
19 + 548201 = 548220
31 + 548189 = 548220
67 + 548153 = 548220
97 + 548123 = 548220
103 + 548117 = 548220
131 + 548089 = 548220
137 + 548083 = 548220

Showing the first eight; more decompositions exist.
