Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152208, here are decompositions:

5 + 152203 = 152208
11 + 152197 = 152208
19 + 152189 = 152208
61 + 152147 = 152208
97 + 152111 = 152208
127 + 152081 = 152208
131 + 152077 = 152208
167 + 152041 = 152208

Showing the first eight; more decompositions exist.
