Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169002, here are decompositions:

11 + 168991 = 169002
59 + 168943 = 169002
89 + 168913 = 169002
101 + 168901 = 169002
103 + 168899 = 169002
109 + 168893 = 169002
139 + 168863 = 169002
151 + 168851 = 169002

Showing the first eight; more decompositions exist.
