Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17888, here are decompositions:

7 + 17881 = 17888
37 + 17851 = 17888
61 + 17827 = 17888
97 + 17791 = 17888
127 + 17761 = 17888
139 + 17749 = 17888
151 + 17737 = 17888
181 + 17707 = 17888

Showing the first eight; more decompositions exist.
