Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169090, here are decompositions:

11 + 169079 = 169090
23 + 169067 = 169090
41 + 169049 = 169090
71 + 169019 = 169090
83 + 169007 = 169090
113 + 168977 = 169090
191 + 168899 = 169090
197 + 168893 = 169090

Showing the first eight; more decompositions exist.
