Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170028, here are decompositions:

7 + 170021 = 170028
37 + 169991 = 170028
41 + 169987 = 170028
71 + 169957 = 170028
109 + 169919 = 170028
137 + 169891 = 170028
139 + 169889 = 170028
191 + 169837 = 170028

Showing the first eight; more decompositions exist.
