Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548162, here are decompositions:

19 + 548143 = 548162
73 + 548089 = 548162
79 + 548083 = 548162
103 + 548059 = 548162
163 + 547999 = 548162
211 + 547951 = 548162
313 + 547849 = 548162
331 + 547831 = 548162

Showing the first eight; more decompositions exist.
