Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169272, here are decompositions:

13 + 169259 = 169272
23 + 169249 = 169272
29 + 169243 = 169272
31 + 169241 = 169272
53 + 169219 = 169272
73 + 169199 = 169272
113 + 169159 = 169272
179 + 169093 = 169272

Showing the first eight; more decompositions exist.
