Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549212, here are decompositions:

19 + 549193 = 549212
43 + 549169 = 549212
73 + 549139 = 549212
193 + 549019 = 549212
199 + 549013 = 549212
211 + 549001 = 549212
379 + 548833 = 549212
421 + 548791 = 549212

Showing the first eight; more decompositions exist.
