Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10888, here are decompositions:

5 + 10883 = 10888
29 + 10859 = 10888
41 + 10847 = 10888
89 + 10799 = 10888
107 + 10781 = 10888
149 + 10739 = 10888
179 + 10709 = 10888
197 + 10691 = 10888

Showing the first eight; more decompositions exist.
