Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169788, here are decompositions:

5 + 169783 = 169788
11 + 169777 = 169788
19 + 169769 = 169788
37 + 169751 = 169788
79 + 169709 = 169788
97 + 169691 = 169788
107 + 169681 = 169788
127 + 169661 = 169788

Showing the first eight; more decompositions exist.
