Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161088, here are decompositions:

17 + 161071 = 161088
29 + 161059 = 161088
41 + 161047 = 161088
71 + 161017 = 161088
79 + 161009 = 161088
107 + 160981 = 161088
181 + 160907 = 161088
211 + 160877 = 161088

Showing the first eight; more decompositions exist.
