Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550980, here are decompositions:

7 + 550973 = 550980
11 + 550969 = 550980
19 + 550961 = 550980
29 + 550951 = 550980
41 + 550939 = 550980
43 + 550937 = 550980
71 + 550909 = 550980
137 + 550843 = 550980

Showing the first eight; more decompositions exist.
