Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11198, here are decompositions:

37 + 11161 = 11198
67 + 11131 = 11198
79 + 11119 = 11198
127 + 11071 = 11198
139 + 11059 = 11198
151 + 11047 = 11198
211 + 10987 = 11198
241 + 10957 = 11198

Showing the first eight; more decompositions exist.
