Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549990, here are decompositions:

11 + 549979 = 549990
13 + 549977 = 549990
41 + 549949 = 549990
47 + 549943 = 549990
53 + 549937 = 549990
79 + 549911 = 549990
107 + 549883 = 549990
113 + 549877 = 549990

Showing the first eight; more decompositions exist.
