Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988266, here are decompositions:

23 + 988243 = 988266
29 + 988237 = 988266
47 + 988219 = 988266
53 + 988213 = 988266
67 + 988199 = 988266
109 + 988157 = 988266
137 + 988129 = 988266
157 + 988109 = 988266

Showing the first eight; more decompositions exist.
