Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152180, here are decompositions:

97 + 152083 = 152180
103 + 152077 = 152180
139 + 152041 = 152180
151 + 152029 = 152180
163 + 152017 = 152180
211 + 151969 = 152180
241 + 151939 = 152180
271 + 151909 = 152180

Showing the first eight; more decompositions exist.
