Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152148, here are decompositions:

37 + 152111 = 152148
67 + 152081 = 152148
71 + 152077 = 152148
107 + 152041 = 152148
109 + 152039 = 152148
131 + 152017 = 152148
179 + 151969 = 152148
181 + 151967 = 152148

Showing the first eight; more decompositions exist.
