Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549228, here are decompositions:

7 + 549221 = 549228
59 + 549169 = 549228
61 + 549167 = 549228
67 + 549161 = 549228
79 + 549149 = 549228
89 + 549139 = 549228
107 + 549121 = 549228
131 + 549097 = 549228

Showing the first eight; more decompositions exist.
