Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 552978, here are decompositions:

7 + 552971 = 552978
61 + 552917 = 552978
79 + 552899 = 552978
131 + 552847 = 552978
137 + 552841 = 552978
157 + 552821 = 552978
191 + 552787 = 552978
227 + 552751 = 552978

Showing the first eight; more decompositions exist.
