Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109888, here are decompositions:

5 + 109883 = 109888
29 + 109859 = 109888
41 + 109847 = 109888
47 + 109841 = 109888
59 + 109829 = 109888
137 + 109751 = 109888
167 + 109721 = 109888
227 + 109661 = 109888

Showing the first eight; more decompositions exist.
