Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549980, here are decompositions:

3 + 549977 = 549980
31 + 549949 = 549980
37 + 549943 = 549980
43 + 549937 = 549980
97 + 549883 = 549980
103 + 549877 = 549980
163 + 549817 = 549980
229 + 549751 = 549980

Showing the first eight; more decompositions exist.
