Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161098, here are decompositions:

5 + 161093 = 161098
11 + 161087 = 161098
59 + 161039 = 161098
89 + 161009 = 161098
101 + 160997 = 161098
131 + 160967 = 161098
191 + 160907 = 161098
257 + 160841 = 161098

Showing the first eight; more decompositions exist.
