Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161010, here are decompositions:

13 + 160997 = 161010
29 + 160981 = 161010
41 + 160969 = 161010
43 + 160967 = 161010
103 + 160907 = 161010
107 + 160903 = 161010
127 + 160883 = 161010
131 + 160879 = 161010

Showing the first eight; more decompositions exist.
