Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161148, here are decompositions:

7 + 161141 = 161148
11 + 161137 = 161148
61 + 161087 = 161148
89 + 161059 = 161148
101 + 161047 = 161148
109 + 161039 = 161148
131 + 161017 = 161148
139 + 161009 = 161148

Showing the first eight; more decompositions exist.
