Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549394, here are decompositions:

3 + 549391 = 549394
71 + 549323 = 549394
113 + 549281 = 549394
137 + 549257 = 549394
173 + 549221 = 549394
191 + 549203 = 549394
227 + 549167 = 549394
233 + 549161 = 549394

Showing the first eight; more decompositions exist.
