Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179198, here are decompositions:

31 + 179167 = 179198
37 + 179161 = 179198
79 + 179119 = 179198
109 + 179089 = 179198
157 + 179041 = 179198
211 + 178987 = 179198
277 + 178921 = 179198
367 + 178831 = 179198

Showing the first eight; more decompositions exist.
