Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550998, here are decompositions:

5 + 550993 = 550998
29 + 550969 = 550998
37 + 550961 = 550998
47 + 550951 = 550998
59 + 550939 = 550998
61 + 550937 = 550998
89 + 550909 = 550998
137 + 550861 = 550998

Showing the first eight; more decompositions exist.
