Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169072, here are decompositions:

3 + 169069 = 169072
5 + 169067 = 169072
23 + 169049 = 169072
53 + 169019 = 169072
173 + 168899 = 169072
179 + 168893 = 169072
269 + 168803 = 169072
311 + 168761 = 169072

Showing the first eight; more decompositions exist.
