Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161068, here are decompositions:

29 + 161039 = 161068
59 + 161009 = 161068
71 + 160997 = 161068
101 + 160967 = 161068
191 + 160877 = 161068
227 + 160841 = 161068
239 + 160829 = 161068
251 + 160817 = 161068

Showing the first eight; more decompositions exist.
