Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161052, here are decompositions:

5 + 161047 = 161052
13 + 161039 = 161052
19 + 161033 = 161052
43 + 161009 = 161052
71 + 160981 = 161052
83 + 160969 = 161052
149 + 160903 = 161052
173 + 160879 = 161052

Showing the first eight; more decompositions exist.
