Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558978, here are decompositions:

5 + 558973 = 558978
31 + 558947 = 558978
41 + 558937 = 558978
47 + 558931 = 558978
97 + 558881 = 558978
109 + 558869 = 558978
149 + 558829 = 558978
151 + 558827 = 558978

Showing the first eight; more decompositions exist.
