Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549558, here are decompositions:

5 + 549553 = 549558
7 + 549551 = 549558
11 + 549547 = 549558
41 + 549517 = 549558
47 + 549511 = 549558
109 + 549449 = 549558
127 + 549431 = 549558
137 + 549421 = 549558

Showing the first eight; more decompositions exist.
