Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7198, here are decompositions:

5 + 7193 = 7198
11 + 7187 = 7198
47 + 7151 = 7198
71 + 7127 = 7198
89 + 7109 = 7198
179 + 7019 = 7198
197 + 7001 = 7198
227 + 6971 = 7198

Showing the first eight; more decompositions exist.
