Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558888, here are decompositions:

7 + 558881 = 558888
19 + 558869 = 558888
59 + 558829 = 558888
61 + 558827 = 558888
97 + 558791 = 558888
101 + 558787 = 558888
107 + 558781 = 558888
131 + 558757 = 558888

Showing the first eight; more decompositions exist.
