Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550986, here are decompositions:

13 + 550973 = 550986
17 + 550969 = 550986
47 + 550939 = 550986
83 + 550903 = 550986
127 + 550859 = 550986
173 + 550813 = 550986
197 + 550789 = 550986
223 + 550763 = 550986

Showing the first eight; more decompositions exist.
