Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169998, here are decompositions:

7 + 169991 = 169998
11 + 169987 = 169998
41 + 169957 = 169998
47 + 169951 = 169998
61 + 169937 = 169998
79 + 169919 = 169998
89 + 169909 = 169998
107 + 169891 = 169998

Showing the first eight; more decompositions exist.
