Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549172, here are decompositions:

3 + 549169 = 549172
5 + 549167 = 549172
11 + 549161 = 549172
23 + 549149 = 549172
83 + 549089 = 549172
101 + 549071 = 549172
149 + 549023 = 549172
263 + 548909 = 549172

Showing the first eight; more decompositions exist.
