Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549306, here are decompositions:

47 + 549259 = 549306
59 + 549247 = 549306
103 + 549203 = 549306
113 + 549193 = 549306
137 + 549169 = 549306
139 + 549167 = 549306
157 + 549149 = 549306
167 + 549139 = 549306

Showing the first eight; more decompositions exist.
