Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169172, here are decompositions:

13 + 169159 = 169172
43 + 169129 = 169172
61 + 169111 = 169172
79 + 169093 = 169172
103 + 169069 = 169172
109 + 169063 = 169172
163 + 169009 = 169172
181 + 168991 = 169172

Showing the first eight; more decompositions exist.
