Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177198, here are decompositions:

31 + 177167 = 177198
67 + 177131 = 177198
71 + 177127 = 177198
89 + 177109 = 177198
97 + 177101 = 177198
107 + 177091 = 177198
179 + 177019 = 177198
191 + 177007 = 177198

Showing the first eight; more decompositions exist.
