Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160290, here are decompositions:

37 + 160253 = 160290
47 + 160243 = 160290
59 + 160231 = 160290
73 + 160217 = 160290
83 + 160207 = 160290
89 + 160201 = 160290
107 + 160183 = 160290
127 + 160163 = 160290

Showing the first eight; more decompositions exist.
