Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549250, here are decompositions:

3 + 549247 = 549250
29 + 549221 = 549250
47 + 549203 = 549250
83 + 549167 = 549250
89 + 549161 = 549250
101 + 549149 = 549250
179 + 549071 = 549250
227 + 549023 = 549250

Showing the first eight; more decompositions exist.
