Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549220, here are decompositions:

17 + 549203 = 549220
53 + 549167 = 549220
59 + 549161 = 549220
71 + 549149 = 549220
131 + 549089 = 549220
149 + 549071 = 549220
197 + 549023 = 549220
257 + 548963 = 549220

Showing the first eight; more decompositions exist.
