Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180252, here are decompositions:

5 + 180247 = 180252
11 + 180241 = 180252
13 + 180239 = 180252
19 + 180233 = 180252
31 + 180221 = 180252
41 + 180211 = 180252
71 + 180181 = 180252
73 + 180179 = 180252

Showing the first eight; more decompositions exist.
