Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172080, here are decompositions:

11 + 172069 = 172080
31 + 172049 = 172080
53 + 172027 = 172080
59 + 172021 = 172080
71 + 172009 = 172080
79 + 172001 = 172080
151 + 171929 = 172080
157 + 171923 = 172080

Showing the first eight; more decompositions exist.
