Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105198, here are decompositions:

31 + 105167 = 105198
61 + 105137 = 105198
101 + 105097 = 105198
127 + 105071 = 105198
167 + 105031 = 105198
179 + 105019 = 105198
199 + 104999 = 105198
211 + 104987 = 105198

Showing the first eight; more decompositions exist.
