Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108198, here are decompositions:

5 + 108193 = 108198
7 + 108191 = 108198
11 + 108187 = 108198
19 + 108179 = 108198
37 + 108161 = 108198
59 + 108139 = 108198
67 + 108131 = 108198
71 + 108127 = 108198

Showing the first eight; more decompositions exist.
