Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161032, here are decompositions:

23 + 161009 = 161032
149 + 160883 = 161032
191 + 160841 = 161032
251 + 160781 = 161032
281 + 160751 = 161032
293 + 160739 = 161032
383 + 160649 = 161032
449 + 160583 = 161032

Showing the first eight; more decompositions exist.
