Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549978, here are decompositions:

29 + 549949 = 549978
41 + 549937 = 549978
67 + 549911 = 549978
101 + 549877 = 549978
139 + 549839 = 549978
211 + 549767 = 549978
227 + 549751 = 549978
229 + 549749 = 549978

Showing the first eight; more decompositions exist.
