Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549874, here are decompositions:

11 + 549863 = 549874
41 + 549833 = 549874
107 + 549767 = 549874
137 + 549737 = 549874
167 + 549707 = 549874
173 + 549701 = 549874
191 + 549683 = 549874
233 + 549641 = 549874

Showing the first eight; more decompositions exist.
