Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161122, here are decompositions:

29 + 161093 = 161122
83 + 161039 = 161122
89 + 161033 = 161122
113 + 161009 = 161122
239 + 160883 = 161122
281 + 160841 = 161122
293 + 160829 = 161122
383 + 160739 = 161122

Showing the first eight; more decompositions exist.
