Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988018, here are decompositions:

11 + 988007 = 988018
47 + 987971 = 988018
89 + 987929 = 988018
107 + 987911 = 988018
149 + 987869 = 988018
167 + 987851 = 988018
197 + 987821 = 988018
359 + 987659 = 988018

Showing the first eight; more decompositions exist.
