Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549828, here are decompositions:

11 + 549817 = 549828
61 + 549767 = 549828
79 + 549749 = 549828
89 + 549739 = 549828
109 + 549719 = 549828
127 + 549701 = 549828
137 + 549691 = 549828
179 + 549649 = 549828

Showing the first eight; more decompositions exist.
