Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159198, here are decompositions:

5 + 159193 = 159198
7 + 159191 = 159198
19 + 159179 = 159198
29 + 159169 = 159198
31 + 159167 = 159198
37 + 159161 = 159198
41 + 159157 = 159198
79 + 159119 = 159198

Showing the first eight; more decompositions exist.
