Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91198, here are decompositions:

5 + 91193 = 91198
47 + 91151 = 91198
59 + 91139 = 91198
71 + 91127 = 91198
101 + 91097 = 91198
179 + 91019 = 91198
227 + 90971 = 91198
251 + 90947 = 91198

Showing the first eight; more decompositions exist.
