Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105888, here are decompositions:

5 + 105883 = 105888
17 + 105871 = 105888
59 + 105829 = 105888
71 + 105817 = 105888
127 + 105761 = 105888
137 + 105751 = 105888
197 + 105691 = 105888
239 + 105649 = 105888

Showing the first eight; more decompositions exist.
