Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152028, here are decompositions:

11 + 152017 = 152028
59 + 151969 = 152028
61 + 151967 = 152028
89 + 151939 = 152028
127 + 151901 = 152028
131 + 151897 = 152028
157 + 151871 = 152028
179 + 151849 = 152028

Showing the first eight; more decompositions exist.
