Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161026, here are decompositions:

17 + 161009 = 161026
29 + 160997 = 161026
59 + 160967 = 161026
149 + 160877 = 161026
197 + 160829 = 161026
269 + 160757 = 161026
317 + 160709 = 161026
389 + 160637 = 161026

Showing the first eight; more decompositions exist.
