Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161046, here are decompositions:

7 + 161039 = 161046
13 + 161033 = 161046
29 + 161017 = 161046
37 + 161009 = 161046
79 + 160967 = 161046
113 + 160933 = 161046
139 + 160907 = 161046
163 + 160883 = 161046

Showing the first eight; more decompositions exist.
