Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180192, here are decompositions:

11 + 180181 = 180192
13 + 180179 = 180192
31 + 180161 = 180192
139 + 180053 = 180192
149 + 180043 = 180192
191 + 180001 = 180192
193 + 179999 = 180192
211 + 179981 = 180192

Showing the first eight; more decompositions exist.
