Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152128, here are decompositions:

5 + 152123 = 152128
17 + 152111 = 152128
47 + 152081 = 152128
89 + 152039 = 152128
101 + 152027 = 152128
191 + 151937 = 152128
227 + 151901 = 152128
257 + 151871 = 152128

Showing the first eight; more decompositions exist.
