Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549198, here are decompositions:

5 + 549193 = 549198
29 + 549169 = 549198
31 + 549167 = 549198
37 + 549161 = 549198
59 + 549139 = 549198
101 + 549097 = 549198
107 + 549091 = 549198
109 + 549089 = 549198

Showing the first eight; more decompositions exist.
