Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162148, here are decompositions:

5 + 162143 = 162148
29 + 162119 = 162148
89 + 162059 = 162148
131 + 162017 = 162148
137 + 162011 = 162148
149 + 161999 = 162148
179 + 161969 = 162148
191 + 161957 = 162148

Showing the first eight; more decompositions exist.
