Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549222, here are decompositions:

19 + 549203 = 549222
29 + 549193 = 549222
53 + 549169 = 549222
59 + 549163 = 549222
61 + 549161 = 549222
73 + 549149 = 549222
83 + 549139 = 549222
101 + 549121 = 549222

Showing the first eight; more decompositions exist.
