Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548156, here are decompositions:

3 + 548153 = 548156
13 + 548143 = 548156
67 + 548089 = 548156
73 + 548083 = 548156
97 + 548059 = 548156
157 + 547999 = 548156
199 + 547957 = 548156
307 + 547849 = 548156

Showing the first eight; more decompositions exist.
