Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161056, here are decompositions:

3 + 161053 = 161056
17 + 161039 = 161056
23 + 161033 = 161056
47 + 161009 = 161056
59 + 160997 = 161056
89 + 160967 = 161056
149 + 160907 = 161056
173 + 160883 = 161056

Showing the first eight; more decompositions exist.
