Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549804, here are decompositions:

37 + 549767 = 549804
53 + 549751 = 549804
67 + 549737 = 549804
71 + 549733 = 549804
97 + 549707 = 549804
103 + 549701 = 549804
113 + 549691 = 549804
137 + 549667 = 549804

Showing the first eight; more decompositions exist.
